|Title||The quality of demographic data on older Africans|
Developing appropriate and equitable policies for older people in Africa requires
accurate and reliable data. It is unclear whether existing data can accurately assess older
African population structures, let alone provide the detailed information needed to
inform policy decision-making.
To evaluate the quality of nationally representative data on older Africans through
examining the accuracy of age data collected from different sources.
To measure the accuracy of age reporting overall we calculate Whipple’s Index, and a
modified Whipple’s Index for older adults, using the single year age-sex distributions
from (a) the household roster of 17 Demographic and Health Surveys (DHS), (b) the
censuses of 12 of these countries, and (c) the Living Standards Measurement Study
(LSMS) for Ethiopia and Niger. We compare reported sex ratios by age.
The quality of age data is very poor for most countries outside Southern Africa,
especially for older adults. In some Sahelian countries DHS surveys appear to omit a
considerable proportion of older women. Data on population structure of older people
by age and sex produced by the DHS and the census are inconsistent and contradictory.
