The resident population of the United States, he told us in a webcast, was 308,745,538. That's an increase of 9.7 percent from the 281,421,906 in the 2000 Census -- the smallest proportional increase than in any decade other than the Depression 1930s but a pretty robust increase for an advanced nation. It's hard to get a grasp on such large numbers. So let me share a few observations on what they mean.
First, the great engine of growth in America is not the Northeast Megalopolis, which was growing faster than average in the mid-20th century, or California, which grew lustily in the succeeding half-century. It is Texas.
Its population grew 21 percent in the last decade, from nearly 21 million to more than 25 million. That was more rapid growth than in any states except for four much smaller ones (Nevada, Arizona, Utah and Idaho).
Texas' diversified economy, business-friendly regulations and low taxes have attracted not only immigrants but substantial inflow from the other 49 states. As a result, the 2010 reapportionment gives Texas four additional House seats. In contrast, California gets no new House seats, for the first time since it was admitted to the Union in 1850.
There's a similar lesson in the fact that Florida gains two seats in the reapportionment and New York loses two.
This leads to a second point, which is that growth tends to be stronger where taxes are lower. Seven of the nine states that do not levy an income tax grew faster than the national average. The other two, South Dakota and New Hampshire, had the fastest growth in their regions, the Midwest and New England.
Altogether, 35 percent of the nation's total population growth occurred in these nine non-taxing states, which accounted for just 19 percent of total population at the beginning of the decade.
My third observation is that immigration is slowing down and may be reversed. Immigration accelerated during the 1990s, and the 2000 Census showed more immigrants than the Census Bureau had estimated.
In contrast, immigration has clearly slowed down since the housing bubble burst and the construction industry went bust in 2007. And the 2010 Census showed fewer residents in several high-immigration states than the Census Bureau had estimated were there in 2009.
