Note: Estimates are for naturalized citizens who naturalized between 1/1/1990 and 7/1/2010

¹Excludes naturalizations of immigrants who arrived before 1990 or who naturalized as children aged 0-17.

²Based on Social Security administration lifetable (Bell and Miller 2005)

³A/R = Ahmed & Robinson 1994 (“low”), SSA = Social Security (Schwabish 2009) (“moderate”), VH = Van Hook et al. 2006 (“high”)

⁴Diff = (ACS - OIS)

⁵%Diff = (ACS - OIS)/OIS * 100

^*Absolute difference between OIS and ACS estimate is greater than twice the standard error of the ACS estimate.
