Age	White Men	White Women	Black Men	Black Women
65	.7	.8	2.8	3.1
70	1.3	1.4	5.0	5.4
75	2.3	2.5	8.7	9.4
80	4.0	4.4	14.8	15.8
85	7.1	7.6	23.9	25.4
90	12.2	13.0	36.3	38.1

Note: All values are weighted. N = 8,946.The prevalence figures are estimates derived from logistic regression model by regressing the log odds of cognitive impairment on age, race, and gender. Interaction between race and gender was tested and was statistically insignificant. Parameter estimates are used to calculate predicted rates.
