I did not find the Indonesia 2000 population census. Is it not available? I only see the 2010 census and the 1995 and 2005 inter census
The Indonesia 2000 population census is available and can be selected if you go to Select Samples first before selecting variables. IPUMS International data is harmonized census information for many countries, which means that there are variables that will contain data for some census samples and not others. My guess is that you did not see Indonesia 2000 because you had a variable selected that does not exist in that sample. For more information, refer to this tutorial on how to use the extract system for IPUMS International.
Thank you! It worked now
