Hello:
Good evening - I am appending / pooling recent surveys from a number of African countries. I realized that the the length of the key stratification variables: IDHSSTRATA and IDHSPSU are different betweeen countries.
According to IPUMS documentation, IDHSSTRATA is supposed to be a 9-character variable, while IDHSPSU is a 10-characters.
But as the following example shows, the character length differs among countries. Does the length have to be the same across countries ? If so, how do I add or subtract characters?
Angola 2015:
Idhspsu = 2401000001
Idhsstrata = 240100018
Lesotho 2014
idhspsu: = 42603000180
Idhsstrata: = 4260300016
Zimbabwe 2015
idhspsu: = 71606000390
Idhsstrata: = 7160600017
thanks - Yawo

Dear Yawo,
Thanks for the question. We will make a change to these variable descriptions.
The lengths of the IDHSPSU and IDHSSTRATA variables do not matter. The important characteristic is that the variables uniquely identify primary sampling units or strata, respectively. This is not affected by their length.
