¹“2005/2006” is defined as the 3rd quarter of 2005 to the 2nd quarter of 2006 in the ENOE, and as May 2005 to April 2006 in the ENADID.

²2009 ENADID Return Migrants are those who emigrated to the U.S. within the last 5 years and returned in the last 12 months and who are still present in the household at survey date in May/June 2009.

³2006 ENADID Return Migrants are those who emigrated to the U.S. within the last 5 years and returned in the last 12 months and who are still present in the household at survey date in April/May 2006.

⁴Ratio calculated from the 1997 ENADID of all migrants returning from the U.S. in the last year to migrants returning from the U.S. in the last year that had been away less than 5 years (authors calculations from the 1997 ENADID). This ratio, applied to the 2006 ENADID migrants (all of whom had left in the last 5 years), produces the estimated “ENOE-equivalent definition” number of 2005/06 return migrants from the ENADID.

⁵The ENOE sample consists of households whose interview number makes them eligible for interview up to the 2nd quarter of 2006. Return Migrants (ENADID equivalent) exclude those return migrants in the 3rd or 4th quarter of 2005 or 1st quarter of 2006 who emigrated again by the 2nd quarter of 2006.

⁶The estimate here differs from the full-sample ENOE estimates of Table 2 due to its being estimated from a sample consisting only of households whose interview number (rotation group) makes them eligible for interview up to the 2nd quarter of 2006. The estimate, however, is scaled up to adjust for the omitted rotation groups, and therefore is an unbiased estimator of the total return migrants in 2005/2006.
