I am trying to delete the PUMAs affected by Hurricane Ketrina in Louisiana --01801, 01802, and 01905 from my analysis. I would also like to delete the same areas in PUMA 1990. How should I match PUMAs in 1990 5% Census and PUMAs in 2000 5% Census in order to delete the correspondent areas in 1990 5% Census?
For example, Lousiana PUMA 1801, which is coded as 221801. (Statefip+PUMA) in 2000.
How should I match the exact puma in 1990? What would be the puma code in 1990?
For PUMA 1801,1802 (in year 2000, Louisiana):
I checked the puma map in 1990 and 2000. The 1990 map did not specify the areas where are coded as 1901-1904 in Louisiana. I do not know how should I relate it to the 2000 map (Louisiana) where 1801-1804 are divided clearly in 4 parts.
For PUMA 1905 (in year 2000, Louisiana)
In 2000 map, it is PLAQUEMINES. In 1990 map, I found 02300 might be similar to the area. But there are two other areas also coded as 02300.
