Examples of survey data and results

One of the most simple descriptive statistics in demography is the population pyramid.  This can be drawn based on data from a sample survey.  In this example we have used data from the 2005 Tanzanian Demographic and Health survey (www.measureDHS.com External link).

DHS have at least three survey forms: a household questionnaire, a women’s questionnaire and a men’s questionnaire.   Information on all household members is collected in the household questionnaire from a single respondent and all resident, adult women are eligible for a more detailed interview.  A sub-sample of all resident, adult men is also interviewed.  

The information needed to draw this graph can be gathered from the household questionnaire:
