Table 5.
Estimated Days of Coastal Recreation per Season and Year for Survey Sample Area
| Season | Mean Days Spent* | Number of Participants** | Estimated Total Days*** |
|---|---|---|---|
| Spring (March, April, May) | 8.95 | 3,401,893 | 30,449,820 |
| Summer (June, July, August) | 18.83 | 4,252,072 | 80,066,906 |
| Fall (September, October, November) | 10.16 | 3,537,166 | 35,946,516 |
| Winter (December, January, February) | 3.29 | 2,981,586 | 9,822,978 |
| 12 month total | 36.83 | 4,629,453 | 170,484,872 |
To eliminate outliers, total days were truncated to remove values >95th percentile. Means of seasonal responses include zeros. When calculating the 12 month mean, seasonal estimates for each person were added to get the 12 month total per respondent. Zeros were not included when calculating the 12 month mean, since by definition a participant needed to spend at least one day recreating in the calendar year.
The number of participants was calculated by using the survey demographic and sampling weights to estimate the number of households in the sample area who participated in each season and in the last 12 months. This was multiplied by 1.91, the number of people age 18 and older per household (from the U.S. Census).
Total days for each season and for 12 months were calculated by multiplying mean days by number of participants.
