Using sample weights. DHS sample weights are used in almost every tabulation in DHS final reports. The few unweighted tables are clearly labeled. Sample weights are described fully in the Guide to DHS Statistics but briefly, weights are used in all analyses to make sample data representative of the entire population. There are different weights for different sample selections/units of analysis:
Sample weights in DHS datasets
Unit of analysis Variable
Households hv005
Household members hv005
Women or children v005
Men mv005
Domestic Violence d005
HIV test results hiv05

like other variables in DHS datasets, decimal points are not included in the weight variable. Analysts need to divide the sampling weight they are using by 1,000,000. Examples:

In Stata:
generate wgt = v005/1000000
tab var [iweight=wgt]
In SPSS:
COMPUTE WGT = V005/1000000.
WEIGHT by WGT.

In SPSS:
WTVAR=V005/1000000
WEIGHT BY WTVAR
