Census Map
 

Pretty cool info here if you're interested in demographic trends. North Carolina is growing quite fast - +18.5% since 2000, and my county has grown +43% in that time - nuts.

Mapping the 2010 U.S. Census - NYTimes.com

I'm wondering about the different rates used there.

Brown County, where I lived, grew at 9.4%.

It shows each racial group's percentage of the overall population, and the change since 2000.

Okay. Is that change in raw numbers, like in thousands of people, or change as a percentage of the population? If so, why is every group in Brown County increasing as a percentage of the population? That doesn't pass the smell test.

My interpretation is that the share of population shown is the current numbers from 2010, but the change from 2000 is reflecting actual numbers of people.

My understanding is that it is showing percentage change since 2000 per race.
So if you lived in the town of Mayberry with 20 people in 2000 (12 white and 8 black), and now Mayberry has 30 people (19 white and 11 blacks), the stats would show up like this:

White: 63% +58%
Black: 37% +38%

Hispanics looking good in Georgia (+96%). My county (Dekalb) shows +3.9%, but whites are down 5% with hispanics and asians up 30% each.

This appears to be the way they're displaying their numbers, yes. I will say, however, that if I ever delivered something this unclear to one of my clients, neither my client nor my boss would be happy. This really needed to be labeled better.

The statistically fun county to see in Georgia (unless you happen to live there I guess) is Clayton. That's where over half the white population (around 30k ppl give or take) left during the past decade, presumably in connection with the unbelievably fucked up school system that ended up losing accreditation for about a year back in '08-'09.

There's too many people nowadays.

So the biggest drop in population I could find is St. Bernard parish in Louisiana - down 46.6% from 2000 - though some of the counties in the Mississippi Delta gave it a close run.

Katrina maybe?

I forgot about that, pretty funny. I was surprised by the areas farther south of the airport, like Fayette, that have pretty large increases in hispanic and asian populations. In not so surprising news, White County is still 95% white :)
