Murdock has also served as the director of the U.S. Census Bureau and says it's pretty clear why so many people want to come to the Houston area: it's the jobs and the economy.
He says many of those new residents came from other states, not other countries.
"Demographers refer to international migration, which is from other counties of course, and domestic migration. And during this period of time from the last census date of April 1st to the date of this particular census release, July 1st, we gained over 290,000 people in Texas from other states."
The U.S. Census Bureau reports Harris County added about 80,000 new resident between July of 2011 and July of last year. The Greater Houston area grew by more than 125,000, second only to the Dallas area.
Murdock says with that growth comes concerns about whether the Houston area can handle the new residents.
"One of the factors that impacts many areas is simply infrastructure. Do you have the roads, do you have the other services to maintain those population bases. So certainly those are things that local jurisdictions involved will have to be sensitive to because people across the country have become aware of what's working and what's not working."
Los Angeles County was second on the Census Bureau's latest list of the fastest growing U.S. counties, adding almost 74,000 residents. Dallas County was fourth on the list.
