Why is the American FactFinder have considerable higher poverty rates than ACS 2014 PUMS


#1

Using the ACS 2014 single year file (downloaded Dec, 1 2015) I got 1,800,773 persons below the 100% poverty level for Los Angeles County while the American FactFinder (also for 2014 single year) shows 1,860,890.

The total population is within .01%

The population where poverty is calculated is within .11%

100% of poverty is over 3%

Creating rates 18.7 (FactFinder) and 18.1 (IPUMS).

This is a considerable difference - more than I usually get.

I have used the same syntax for many years and this syntax seems to be working correctly for the the 2014 5 year file, but I could be making an error.

Using POVERTY <> 0 - You recode 0 to 1 and recode NA to 0 - correct

Below 100% poverty < 100.

Do you have any insight on why my numbers from IPUMS would be so different than the published numbers?

In late December, it was brought to our attention that we had not made a necessary adjustment when calculating the POVERTY variable for 2014. We promptly fixed this issue, but based on the date you provided, you will need to resubmit your data extract. I downloaded a data extract today and confirmed that the LA County poverty rate now matches FactFinder exactly (18.7% below poverty level).

Hope this helps and apologies for any inconvenience this has caused.
