3.128 Suppose that among women who are age 50–74, 22% are age 50–54, 21% are age 55–59, 20% are age 60–64, 19% are age 65–69 and 18% are age 70–74. What is the overall 1-year cumulative incidence among Caucasian women ages 50–74?
Age | incident percent | Cumulative Incident Percent |
50–54 | 22% | 22% |
55–59 | 21% | 43% |
60–64 | 20% | 63% |
65–69 | 19% | 82% |
70–74 | 18% | 100% |
From above table cumulative incident for ages 50-74 is 100%
