According to the 2010 1 year ACS Census Estimates, the ten CDs with the highest percentage of foreign-born residents are:
FL-21 (58.11%)
FL-18 (53.16%)
CA-31 (51.53%)
NY-05 (48.07%)
CA-47 (46.86%)
FL-25 (46.78%)
CA-29 (46.33%)
NY-06 (44.32%)
CA-34 (44.26%)
NY-09 (42.06%)
The ten CDs with the lowest percentage of foreign-born residents are:
KY-05 (0.60%)
WV-03 (0.78%)
OH-18 (0.95%)
MO-08 (1.14%)
OH-04 (1.19%)
PA-12 (1.22%)
WV-01 (1.23%)
OH-06 (1.35%)
MN-08 (1.50%)
PA-09 (1.58%)
Does that include single district states? I'm surprised that Wyoming wouldn't be in the bottom ten.
