Table 2.

Age- and sex-specific average annual incidence rates (per 100,000 person-years) of parkinsonism and its types: Olmsted County, MN, 1976–1990*

SexAge group, yTotal
0–2930–4950–5960–6970–7980–99
* Numbers in parentheses to the right of the rates indicate the actual number of cases. Incidence rates can be recomputed by dividing the number in parentheses by the corresponding denominator listed in the footnotes below (and multiplying by 100,000).
† Denominators (in person-years) for men were as follows: 0–29 = 355,292; 30–49 = 196,090; 50–59 = 59,528; 60–69 = 40,052; 70–79 = 22,367; 80–99 = 9,435.
‡ Denominators (in person-years) for women were as follows: 0–29 = 368,848; 30–49 = 202,605; 50–59 = 61,220; 60–69 = 47,639; 70–79 = 36,709; 80–99 = 24,689.
