The fiscal years do not square precisely with presidential years. Fiscal year 2008 was entirely under Bush, while fiscal year 2009 consisted of four months under Bush and eight under Obama. So using the raw fiscal-year figures doesn't quite prove the Bush-Obama comparison.
It's not clear that Obama policies deserve credit (or blame, depending on your perspective) for any increase in deportations, as Ramos implies. Michelle Mittelstadt, a spokesman for the Migration Policy Institute, said that "deportation numbers have been on a steadily upward trajectory" since 2002, due to a number of policy changes initially undertaken during the Bush administration. Indeed, between 2002 and 2008, deportations rose by 117 percent.
DHS also provided totals for part of fiscal year 2010 -- the portion from Oct. 1, 2009, through June 7, 2010. That number was 227,163. If you prorate that amount to a full 12 months, you get a full-year total of 330,419 -- which is less than each of the two previous years. However, immigration experts said that deportations are not spaced equally throughout the year, meaning that prorating is not necessarily valid.
