Table 1.
Example calculation of age and race/ethnicity specific HIV incidence rates.
| Age group | Proportion of cumulative black male HIV/AIDs cases by age groupa | Number of black males with new diagnoses of HIV/AIDs in SC in 2009b | Calculated number of black male cases of HIV/AIDs in SC in 2009 by age group | SC 2009 black male population by age group | Calculated 2009 SC black male HIV/AIDs incidence rates by age group |
|---|---|---|---|---|---|
| 13–19 | 3.4% | 418 | .034 × 418 = 14.2 | 78,910 | 14.2/78,910 = .018% |
| 20–29 | 28.8% | 418 | .288 × 418 = 120.4 | 104,604 | 120.4/104,604 = .115% |
| 30–39 | 35.3% | 418 | .353 × 418 = 147.6 | 81,714 | 147.6/81,714 = .181% |
| 40–49 | 22.1% | 418 | .221 × 418 = 92.4 | 85,557 | 92.4/85,557 = .108% |
