I saw an article about this in the paper a couple weeks ago, but I just found the information on the
Census website. Their new population estimates are out for metro areas for 2013. Tucson metro area has gained 16,291 people since the 2010 census. Add that to the metro population of 980,263 at that time and our metro population is 996,554 (and an increase of only 1.66% since 2010). We should hit the one million mark next year. But, there are some disturbing facts in the report for Tucson too. The population increase per year for the 3.25 years since the census (4/1/10 - 7/1/13) is 5,012.62 per year. Last year we gained 4,159 - below the average of the first 2.25 years. Also, last year, though our international migration was 1,754 - we lost 980 people to the rest of the country (including other parts of Arizona). This puts our total domestic migration for the 3.25 years since the census at -83, meaning until we were -980 last year, we had actually gained 897 people from the rest of the US before last year. Our international migration in the 3+ years since the census was 5,708 - which makes up almost 1/3 of the total increase in that time.
Phoenix, on the other hand has gained 205,874 total since the census and 78,486 from domestic migration.
