Municipal level obs. = 2455. State level obs. = 32
Municipal level data are from the 2010 Mexican Census. State level data are from annual ENOE surveys
We also compare state level international migration rates from the Census and ENOE. For the 2005–2010 period, the total international migration at the state level from the Census is 3.11%, slightly higher than the ENOE total. Across all states the correlation between the Census & ENOE 5-year international migration rates is 92.1%. For annual international migration rates, correlation between the census and the ENOE is 56.6%
