Change Number of Cases Imported from IPUMS

By default, you get a sample of 500 cases. You can change your sample size to be between 1 and 10,000 cases.

1. In the Microdata panel of the inspector, expand the Choosing Cases list.

2. Select Sample Size.

3. Edit the Maximum Sample Size. (You can't import more than 10,000 cases at a time.)

Some samples (such as those from small states) may not have as many cases as you've specified. This field doesn't determine the number of cases; rather, it sets a limit.

Warning: Fathom slows down significantly with collections of more than a couple thousand cases.
