Abstract
Problem
Since the implementation of the Occupational Safety and Health Act, safety and health in the work environment has seen marked improvement. Although these improvements are laudable, workplace hazards continue to plague the American worker. Understanding the economic burden of fatalities by industry sector is important to setting broad occupational safety and health research priorities. Cost estimates provide additional information about how fatal injuries affect society and hence can improve injury prevention program planning, policy analysis, evaluation, and advocacy.
Method
This study estimated the total, mean, and median societal costs by worker and case characteristic in 2003–2006 for the industry sectors identified in the National Institute for Occupational Safety and Health National Occupational Research Agenda (NORA). Analyses were conducted with restricted access to the Bureau of Labor Statistics Census of Fatal Occupational Injuries data. These data exclude military personnel, decedents with unknown age or sex, and fatalities occurring in New York City. Societal costs were estimated using the cost-of-illness approach, which combines direct and indirect costs to yield an overall cost of an fatal occupational injury.
Results
During this period, the cost of the 22,197 fatal occupational injuries exceeded $21 billion. The mean and median costs of these fatalities were $960,000 and $944,000 respectively. Total societal costs by NORA sector ranged from a high of $5.8 billion in Services to a low of $530 million in Healthcare and Social Assistance with mean costs ranging from the nearly $800,000 in Agriculture, Forestry, and Fishing to almost $1.1 million in Mining.
Discussion
The societal costs—total, mean, and median costs—of case and worker characteristics for occupational fatal injuries varied within each NORA sector.
Impact on Industry
To have the greatest societal impact, these costs can be used to target resources for public and private sector research by industry.

1. Introduction
Mankind has been concerned with the safety and well-being of workers for more than 2,000 years. Most of the earliest accounts focused predominately on health rather than safety issues. With the advent of the industrial revolution, the interest on the relationship between injury and the work environment began to intensify. By 1936, the Walsh-Healey Act provided protection of workers in a broad sense—no work could be performed if the establishment was unsanitary, hazardous, or was dangerous to the worker for federal contracts of over $10,000 (Walsh-Healey, 1936).
The passage of the Occupational Safety and Health (OSH) Act (Public Law 91–596) in 1970 provided a systematic national approach “to assure so far as possible every working man and woman in the Nation safe and healthful working conditions (29 U.S. Code [USC] 671).” The Act devised a three-pronged program to meet the mandate to improve safety and health in general industry and construction (OSH Act, 1970). The Department of Labor housed two of these prongs, the Occupational Safety and Health Administration (OSHA) and the Bureau of Labor Statistics (BLS). OSHA was created as the regulatory arm equipped to promulgate and enforce standards. The BLS was named as the statistical arm to determine the number of occupational injuries and illnesses on a routine basis. The final prong, the National Institute for Occupational Safety and Health (NIOSH), was established to help assure safe and healthful working conditions by providing research, information, education, and training in the field of occupational safety and health (NIOSH, 2012)
To accomplish the charge, NIOSH provides national and world leadership to prevent work-related illness, injury, disability, and death by gathering information, conducting scientific research, and translating the knowledge gained into products and services, including scientific information products, training videos, and recommendations for improving safety and health in the workplace.
In 1996 NIOSH engaged in an innovative public-private partnership to establish priorities for occupational safety and health research both at NIOSH and throughout the country—the National Occupational Research Agenda (NORA). During its first decade, NORA advanced safety and health knowledge in 21 scientific areas by emphasizing priority-driven research. The program entered its second decade in 2006 by focusing national research on the problems of highest relevance to workers, employers and occupational safety and health practitioners in the major industrial sectors to better move research to practice within workplaces (NIOSH, 2009).
The number of work-related injuries and illnesses are collected and published annually by BLS as required under the OSH Act. During the first decade of NORA, the total number and rate per 100 full-time workers of occupational injuries declined by 33% and 39% respectively. In the second decade of NORA through 2010, the number of occupational injuries dropped from 3.9 million in 2006 to 2.9 million in 2010—a 25% decline. During this same time period, the number of days away from work cases for injuries and illnesses were 1.2 million in 2006 and dropped 200,000 by 2010. Moreover, the BLS Census of Fatal Occupational Injuries (CFOI) reported that the number of fatalities declined by 6% during the first decade of NORA and has declined by 22% since the advent of the second decade (BLS, 2011).
However, measures of the human loss—frequency, rate, and severity—describe only a portion of the burden to society. Section (2)(a) of the OSH Act highlighted the need for societal costs by stating “The Congress finds that personal injuries and illnesses arising out of work situations impose a substantial burden upon, and are a hindrance to, interstate commerce in terms of lost production, wage loss, medical expenses, and disability compensation payments.” (OSH Act, 1970). This paper provides the first step in identifying the burden to society by deriving the societal costs of fatal occupational injuries occurring in the U.S. This measure of economic loss or burden adds a valuable dimension to targeting efforts as well as providing input for evaluating the effectiveness of investments in prevention efforts. This study concentrates on determining the societal burden in those areas of NIOSH focus, the NORA industry sectors, and examining the similarities and differences of these costs across the sectors. Presentation of the societal costs of fatal occupational injury by case and demographic characteristics within each NORA industry sector allows policy makers to systematically examine current and potential programs using standard economic measures.
2. Methods
For this study, the costs of fatal occupational injuries were estimated using a model developed by the Division of Safety Research within NIOSH (Biddle, 2004, 2009; Biddle & Keane, 2011). This model uses the cost-of-illness method to estimate the effect on the U.S. Gross Domestic Product (GDP) of a workplace fatality by combining direct and indirect costs to yield an overall societal cost of an fatal occupational injury. The direct and indirect costs of each fatal occupational injury were derived independently and then summed for each demographic and case characteristic.
The nominal value for medical costs in 1998 dollars of $11,276, obtained from the Detailed Claims Information (DCI) database from National Council on Compensation Insurance (Detailed Claims Information, 1992–1995), was the single direct cost used in the study. The dollar value was adjusted to 2006 dollars using the Consumer Price Index-Medical Care Index (BLS, 2009a).
The indirect lifetime cost of an individual fatal occupational injury was derived by calculating the present value of lost household production and future earnings of that worker summed from the year of death until that decedent would have reached age 67, accounting for the probability of survival were it not for the premature death—the human capital approach. The earnings component of the cost model consists of four parts: base wage; fringe benefits; economy-wide productivity growth; and life-cycle wage growth. The base wage of the decedent at the time of death was derived from the BLS Occupational Employment Statistics, a Federal-State cooperative semi-annual establishment survey, which produces state-based occupational wages (BLS, 2009b). Because this survey does not provide wage data by age, the wage value was adjusted to account for the age of the decedent at the time of death using a NIOSH developed algorithm (Biddle & Keane, 2011). The base wage was also adjusted to include the value of employee fringe benefits using BLS Employer Cost for Employee Benefits data from the National Compensation Survey Program (BLS, 2009c). The BLS Employment Cost Index (BLS, 2009d) was used to estimate the amount that wages increased in concert with the growth of the U.S. economy as a whole. To account for the final component of wage growth, estimates of the life-cycle growth – the salary growth due to individual worker experience – were used to adjust the base wage. The non-market losses or loss of household production were derived from time-diary data captured in the National Human Activity Pattern Survey study commissioned by the Environmental Protection Agency (Expectancy Data, 2000).
Mathematically the indirect cost calculation is represented as follows:
where:
| PVF | present discounted value of loss per person due to an individual fatal occupational injury | |
| Py,q,s(n) | probability that a person of age y, race q, and sex s will survive to age n | |
| q | race of the individual decedent | |
| s | sex of the individual decedent | |
| n | age if the individual had survived | |
| Ys, j(n) | median annual compensation of an employed person of sex s, specific occupation j, and age n (includes median annual earnings, benefits, and wage growth adjustments) | |
| j | specific occupation of individual at death | |
|
|
mean annual imputed value of household production h of a person of sex s, and age n | |
| g | earnings growth rate attributable to overall productivity | |
| y | age of the individual at death | |
| r | real discount rate (3%) |
A hypothetical example calculation would best illustrate how this model operates. In this hypothetical example, the decedent is a 44 year-old white male carpenter in construction who was injured in Alabama and died in 2004. The calculations are illustrated for each component of the formula for the first two iterations (for ages 44 and 45) following the fatality below. The second iteration would be repeated 22 more times or until the decedent would have reached age 67.

The following are used in calculations for the first year only.
$11,276 Medical cost with an adjustment of 0.7807159 from the Medical Care Consumer Product Index.
For the first year estimate, the wage, benefit, and household production values are summed and multiplied by the probability of survival (determined by the age of the person at the time of death), which is then discounted at a 3% rate and added to the fixed medical cost adjusted for medical inflation. In the second year the wage, benefit, and household production values are summed and multiplied by the probability of survival (determined by the age of the person one year from the time of death), which is then discounted at a 3% rate for the second year estimate. In subsequent years, the process remains the same except for adjusting the discount rate superscript to the iteration calculation number minus 1.
The first year calculation of (0.99675*(((27090*1.2176005/0.937176)*(1.000897*(((1.008627-1)/2) +1)))+((27090*1.2176005/0.937176)*(0.1925*1.007183))+((10278.4/0.828138)*(1.000897))))/1.03̂0+(11276/0.7807159) yields a total of $81,314.16.
The second year calculation of (0.99647*(((27090*1.2176005/0.937176)*(1.000897*(((1.008627-1)/2)+1))*(1.001794*0.986751))+ (((27090*1.2176005/0.937176)*(1.000897*(((1.008627-1)/2)+1)))* (1.001794*0.986751)*(0.20425*1.014367))+((10716.4/0.828138)* (1.001794))))/1.03̂1 yields a total of $66,350.05.
The resulting two year PVF for this specific hypothetical fatal occupational injury is $81,314.16+$66,350.05 or $147,664.21.
Fatal injury data for each decedent was obtained with restricted access to the BLS Census of Fatal Occupational Injuries (CFOI) program data for 2003–2006 (BLS, 2009e). This census compiles data from 50 States and the District of Columbia using multiple sources, such as death certificates, medical examiner records, newspaper accounts, and workers’ compensation claims for decedents of any age as long as the death was a work-related fatal injury occurring in the U.S. Decedents less than 16 years of age, of unknown age or sex, identified as members of the U.S. military, and fatalities occurring in New York City were not included in the cost calculations in this study. Because of these constraints, the number of occupational fatal injuries may not match those published by BLS. Additionally, the views expressed here do not necessarily reflect the views of the BLS.
Societal costs were calculated for case and demographic characteristics of decedents employed in the NIOSH NORA Sectors at the time of their death. These industry sector groups were defined in 2006 following the North American Industry Classification System (NAICS) which identifies 20 sectors. NIOSH aggregated industries into eight broad defined Sectors in Table 1.
Table 1.
NAICS1 Codes of Industries Included in the NIOSH NORA Sectors.
| NORA Sector | NAICS Codes1 |
|---|---|
| Agriculture, Forestry, and Fishing | 11 |
| Construction | 23 |
| Healthcare and Social Assistance | 62 |
| Manufacturing | 31–33 |
| Mining | 21 |
| Services | 51–56, 61, 71–72, 81 and 92 |
| Transportation, Warehousing, and Utilities | 48–49 and 22 |
| Wholesale and Retail Trade | 42 and 44–45 |
The event or exposure in the CFOI describes the manner in which the injury was produced or inflicted and is coded based on the Occupational Injury and Illness Classification System (OIICS) Manual (BLS, 2007). The 2000 Standard Occupational Classification (SOC) system was used by BLS to classify decedents into occupational categories (Office of Management and Budget, 2000).
3. Results
During the 4-year period from 2003 to 2006, there were over 22,197 occupational fatal injuries, with a total societal cost of over $21billion. The overall mean and median costs for these fatalities were $960,000 and $944,000 respectively (Table 2). The majority of the decedents were male (20,536 males compared to 1,661 females) but females had a higher mean cost ($950,000 for males compared to $1,085,000 for females). Over 80% of the decedents were White, which also carried the highest mean and median values. Nearly half of the decedents (47%) were between 35 and 54 years old at the time of death, while their total societal cost contributed over half (57%) of the total loss. Occupations in the Natural resources, construction, and maintenance occupational group had the highest number of fatalities and total costs, but the occupational group of Management, professional and related occupations had the highest mean and median values. The leading event or exposure was Transportation accidents, accounting for 40% of the total fatalities and 40% of the associated total societal cost. However, they carried the fourth highest mean cost and the third highest median cost.

In the Agriculture, Forestry and Fishing sector, the total cost of all fatal occupational injuries was just over $2 billion, with mean and median costs of $777,000 and $710,000 respectively (Table 3). The highest mean value was associated with the occupational group with the least number of fatalities—Production, transport, and material moving occupational group. The occupational group of Natural resources, construction, and maintenance accounted for over 40% of the fatalities but had the lowest mean value, which was 70% of the highest mean value.
Falls (31%), Transportation accidents (27%), and Contact with objects and equipment (20%) events or exposures accounted for the majority of the $5.1 billion total cost of occupational fatal injuries in the Construction sector (Table 4). However, Assaults and violent acts carried the highest mean cost of any event or exposure category at $1.2 million per fatality. Males comprised the overwhelming majority (98%) of the total burden of the fatalities in the Construction sector, but experienced a mean and median cost slightly lower than females.

The Management, professional and related occupations occupational group had the largest number of occupational fatalities as well as the largest proportion (77%) of the overall societal cost in the Healthcare and Social Assistance sector (Table 5). This group also experienced the highest mean and median costs approaching double the magnitude of the smallest costs in Service occupations. The overwhelming majority of the total costs were found in two event or exposure categories—Transportation accidents (53%) and Assaults and violent acts (27%).

Transportation accidents had the largest number of fatal occupational injuries in the Mining sector, followed closely by Contact with objects and equipment (Table 7). These two event or exposure categories also had the highest total societal cost (accounting for nearly 70% of all costs in this sector). The event or exposure category with the lowest total cost, Falls, had the highest mean cost of $1.1 million. The remaining event or exposure categories presented had mean and median costs that exceeded $1 million.

The Services sector experienced the highest number of fatal occupational injuries in the occupational group of Service and related occupations, which also had the largest total societal costs (Table 8). However, the occupational group of Management, professional and related occupations had the highest mean and median costs. The mean cost of this group was substantially higher than other groups—nearly 1–1/2 times the lowest mean cost and 1-1/3 times the next highest mean cost. Five of the 7 event or exposure categories had a mean cost of greater than $1 million.

Transportation accidents had the highest total cost of fatal occupational injuries as well as the largest number of fatalities in the Transportation, Warehousing, and Utilities sector, accounting for nearly 3/4 of the total count and burden within the sector (Table 9). Females had a mean cost 20% higher than males and a median cost 12% higher than males. Decedents with a reported race category of “Other” had a mean cost higher than any other race category—7% higher than White and 16% higher than Black.

The Wholesale and Retail Trade sector saw nearly half of the occupational fatal injuries occurring to those workers in the occupational group of Sales and office occupations (Table 10). The Management, professional and related occupations occupational group had a mean cost nearly double the cost of the next highest occupation group, Natural resources, construction, and maintenance group. Event or exposure categories had a mean cost of under $1 million. The highest mean cost (Fires and explosions) was nearly 1-1/2 times the lowest cost (Bodily reaction and exertion).
4. Discussion
The societal toll of fatal occupational injury is substantial—over $21 billion in this 4 year period, but it was not evenly allocated among NORA industry sectors. The total societal costs ranged from a low of $530 million in Healthcare and Social Assistance to a high of $5.8 billion in Services. To a large extent the variation is due to the number of fatalities occurring in each of the NORA industry sectors; Services had the highest number of fatalities while Healthcare and Social Assistance had the lowest. However, it should be noted that the distribution of the number and total costs of these fatalities by NORA industry sector are not identical. The Agriculture, Forestry, and Fishing sector constituted 12% of the occupational fatal injuries, but only 10% of the total costs. Conversely, the Construction sector accounted for 22% of the number of fatal injuries but a larger portion, 24%, of the total burden. The varying mean costs across industry sectors contributed substantially to creating these differing proportions of the total societal burden.
The range of mean societal costs was considerable, with Mining almost 1-1/2 times greater than the industry sector with the lowest mean value—Agriculture, Forestry, and Fishing (Table 11). Four of the industry sectors’ mean costs were less than $1 million and four were more than $1 million per fatal injury, but only two industry sectors had median costs above $1 million. All but two industry sectors, Mining and Transportation, Warehousing, and Utilities, had median costs that were lower than their mean costs. Mining and Construction sectors had the highest median costs. Mining and Construction also had the smallest difference between mean and median costs—pointing to a more normal distribution of those individual average costs. The difference between the mean and median costs across all industry sectors ranged from less than 1% (Mining sector) to just over 9% in the Healthcare and Social Assistance and Agriculture, Forestry, and Fishing sectors.

There are many similarities in the cost estimate patterns by demographic and case characteristics among the NORA industry sectors, which suggest that research in these areas would be most beneficial to all industry sectors. The pattern for the burden by sex was consistent throughout the industries—males had the highest number of fatalities and the greatest total cost, while females had the highest mean and median costs. There was a single exception—Healthcare and Social Assistance—where females had not only the highest mean and median costs, but also the highest total cost while males had the highest number of fatalities.
In all industry sectors, the White race category had the largest number of fatalities and the highest total costs. In four of the sectors, Construction, Manufacturing, Services, and Wholesale and Retail Trade, the White race category also had the highest mean and median costs. Other sector mean and median highs were in the race category “Other” except Mining where the highest mean and median costs were found in the Black race category.
The highest burden in all of the cost categories was found in the middle age groups—25–34 years, 35–44 years, and 45–54 years—with the greatest burden falling into the 35–44 age group. In five of the industry sectors, the total, mean and median cost was highest in the 35–44 years age category. Furthermore, the mean cost was highest for the 35–44 years category in all but one industry sector, Transportation, Warehousing, and Utilities, where the highest mean was found in the younger age category of 25–34 years old. The older age group, 45–54 years, had the highest total and median costs in Agriculture, Forestry, and Fishing as well as the highest total cost in Healthcare and Social Assistance.
Although similarities among the industry sectors can be found in the case characteristic of event or exposure, they are far less pervasive than among worker demographic characteristics. Only three of the NORA sectors—Services; Transportation, Warehousing, and Utilities; and Wholesale and Retail Trade—had sufficient fatalities in all seven event or exposure categories to meet publication criteria. Transportation accidents had the highest total societal cost in six of the eight NORA industry sectors, and in the remaining two sectors the category had the second highest total cost. Although the mean cost of an event or exposure varied among industry sectors, Assaults and Violent Acts were highest in 50% of the industry sectors.
Understanding that the magnitude of the costs derived by this model is largely dependent on the compensation and age of the decedent helps to explain some of the variation in these cost estimates. More specifically, a greater societal burden is estimated when the decedent was employed in an occupation that provides higher compensation and was in the middle age groups at the time of death. Worker compensation is driven by the worker occupation, the industry, and state in which they were employed. Therefore, to fully understand why specific case and worker characteristics produce higher or lower societal costs, more detailed estimates and analysis than provided in this paper must be derived. However, some generalized information can be gleaned from the age of the decedent. Among event or exposure categories the cost of Assaults and Violent Acts has the highest mean cost in the Construction and Services sectors. In each of these sectors, half of the decedents were in the age groups (25–34 and 35–44) with the highest mean cost. This can be compared to the Agriculture, Forestry, and Fishing sector where only 19% were in those age categories and the mean cost for Assaults and Violent Acts was the second lowest cost.
As the characteristics and conditions of the workplace changes, the societal costs of fatal injuries will respond accordingly. Fatalities are associated with the characteristics of the job and the characteristics of the worker. In 2010, the Bureau of Labor Statistics reported that a “rising labor force participation among older persons is likely part of a long-term pattern that began in the mid-1990s”. The participation rate for those 55 and older has jumped from 29 percent in May, 2009 to 40 percent in February, 2010. Furthermore, currently those over 65 years old had a fatality rate of 11.9 per 100,000 full-time equivalent workers in 2010—3 times higher than the rate for all workers— and those aged 55–64 years old had the second highest rate of 4.7 (BLS, 2012). In addition, changes in the overall health status of our aging workforce, such as increased rates of diabetes and obesity, will most likely increase the risk occupational fatal injuries. As the workforce becomes older, the societal impact generated from this model should be reduced as the formula stops aggregating burden at age 67. However, the change in societal costs will depend on the wages of the occupations in which they are employed at the time of their death. If a worker retires from a full-time highly paid occupation but continues working in a part-time minimum wage occupation, the reduction will be much less than if they remained in their occupation throughout their life. Changes in the work environment will also impact the burden. Currently, the high growth rates for employment are found in the Health Care and Services sectors—both having higher mean costs than most sectors. However, these sectors have traditionally had lower fatality rates and counts. Ultimately, the changes in the burden of fatal occupational injury derived by this model will be determined by the compensation and age associated with the decedent.
The cost model used in this study produced a conservative estimate for the societal costs of fatal occupational injuries. Moreover, these estimates are not exact; they are approximations based on many factors and are subject to limitations of the model specification and limitations associated with the data inputs. Cost estimates presented are limited as compensation data frequently underestimates the value of youth and other working minority groups. The model does not provide a mechanism to identify changes in career, less than full-time employment, or compensation for multiple job holders. Additionally, the model does not provide a comprehensive cost of occupational fatalities as only a single direct cost category is included in the calculations.
5. Summary
In general, cost estimates provide additional information about how injuries affect society. They represent income that is not received and medical expenses incurred because of fatal injuries and the effect on the GDP and other national economic measures in the U.S. These cost estimates can be used to improve occupational injury prevention program planning, policy analysis, evaluation of safety and health interventions, and advocacy for a safer work environment. They can be used to assist targeting resources for research, both in the public and private sector. They can demonstrate the value of the research directions identified through the NORA efforts as measured by the impact on GDP.
This study demonstrates that not only do industry sectors vary by worker characteristics, industrial function, and safety and health risks, but they vary by the economic losses from occupational fatal injuries. These findings suggest that research efforts to prevent fatal occupational injuries should be identified and conducted within each industry sector independently—as is being done in the NORA process. The study points to areas, such as those with the highest mean costs or total costs, which should be examined more closely to determine where research would best focus on the problems of today’s workplaces. Many broad research directions would remain the same as identified by the NORA activity, but those with a greater burden can be highlighted for more immediate targeting. For example, across all industry sectors transportation events have the highest total burden. As a result, it can be suggested that motor vehicle research is needed to assess the effects of electronic devices or information systems in the vehicle on driver attention to the driving task and the risk or occurrence of motor vehicle crashes. In the Services industry, mean costs suggest that assessing the effects of long or irregular hours of work, long hours of driving, or fatigue/sleepiness on motor vehicle crashes, particularly in worker populations such as emergency responders and sales workers should be conducted. Within the Mining sector, researchers should focus on developing activity-specific engineering and process controls in the Oil and Gas industry to limit air contaminant release from process equipment and site environments to prevent exposures to chemical hazards during well servicing operations. Finally, in the Construction sector, research exploring methods to encourage workers to use fall-protection equipment could assist in reducing the overall cost of fatal occupational injury by reducing or eliminating those incidents. Deriving the cost of fatal occupational injury at more detailed levels of case characteristics, such as the types of motor vehicle crashes and who are the perpetrators of assaults and violent acts within industry sectors, would provide more information on where focusing research would reduce the greatest burden, both in human and economic measures.
