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?
