New estimates from the U.S. Census Bureau say that Portland's growth cooled a bit from 2015 to 2016, but continued its blistering post-Great Recession pace of more than 1 percent a year.
The census released its 2016 estimates on Thursday. The bureau said the population of Portland proper on July 1, 2016, was 639,863. That's a 9,242-person increase from July 2015, and more than 56,000 greater than the headcount in the 2010 Census.
About 37.5 percent of the population growth in the tri-county area this decade has been in Portland proper, the bureau estimates.
