Boise (670 KBOI News) – With one year to go until the 2020 US Census, the Treasure Valley’s community planning association is making an educated guess at how many people are living here.

COMPASS, the Community Planning Association of Southwest Idaho, is estimating the total population of Ada and Canyon Counties together is 712,200.

They start with the 2010 Census numbers, then factor in things like building permits issued, vacancy rates, and annexations.

They estimate Boise’s population at 236,310. Meridian is estimated at 114,680, and Nampa is only the third Idaho city to surpass 100,000, at an estimated 102,000.

The report points out that since the year 2000, Nampa has nearly doubled in size, and that Meridian has added over 14,000 citizens just since last year.

Putting it all in perspective, in 1990, the US Census found the total population of the Treasure Valley was roughly 296,000.
