Limited data sets for use with online data analylsis system?

Hi all,

I’m new to IPUMS. Can someone explain to me why only a limited number of datasets are available for use with the online data analysis system?

Thanks,

Blake

There is one sample for every decennial census or ACS year from 1850 to the present in SDA. If you’re interested in a different sample for a given year you may access it through the extract system.
