The overall population over the past 10 years dropped slightly in Brookfield, Riverside and North Riverside, while an increasing percentage of those populations identified themselves as minorities, with the sharpest increase among Latinos and Asians.

The U.S. Census Bureau released its first batch of local data last week for the 2010 national count. The numbers for Riverside, Brookfield and North Riverside in some ways mirrored what transpired in Chicago and suburban Cook County. Overall population fell off as people headed to the collar counties.

Riverside’s total count fell slightly to 8,875 from its 2000 population of 8,895, and North Riverside saw its population dip to 6,672 from its 200 total of 6,688. Brookfield saw its population decline from 19,085 in 2000 to 18,978 in 2010.

In Cook County, overall population declined from 5.4 million in 2000 to 5.2 million in 2010. At the same time, the collar counties saw their collective population increase from 8.1 million to 8.3 million in 10 years.

The city of Chicago saw its total population fall by more than 200,000 people, or 6 percent, from 2.9 million in 2000 to 2.7 million in 2010. In Chicago, at least, that decline was reflected across all but two groups, Asians and Latinos.

The white populations of Riverside, Brookfield and North Riverside all fell, mirroring what took place throughout northeast Illinois from 2000 to 2010.

Ten years ago, whites made up 92 percent of the total population in Riverside, 89 percent in Brookfield and 86 percent in North Riverside. In 2010, those percentages fell, respectively, to 85, 78 and 67 percent.

Meanwhile, the city of Chicago’s black population fell by more than 181,000 residents.

But based on the census figures, it’s tough to tell exactly where the city’s black population landed. While some suburban Cook County municipalities saw the number of black residents increase in the past 10 years, the black population in both suburban Cook County and the collar counties fell from 2000 to 2010, according to the Census Bureau.

Certainly, the black population in some inner-ring suburbs increased. Berwyn and Cicero saw their black populations swell by more than 2,000 each. And the black populations in Brookfield, Riverside and North Riverside all increased.

In 2000, just 23 people in Riverside identified themselves as black. In 2010, that number grew to 110. The number represents just 1.2 percent of Riverside’s total population, but it is still an almost 400-percent increase in the number of black residents residing in Riverside.

Similarly, the black population in North Riverside more than doubled from 197 in 2000 to 412 in 2010. Blacks now make up 6.2 percent of the village’s population. Brookfield counted 456 black residents in 2010, compared to 165 in 2000.

While both white and black populations declined in the six-county area that comprises the Chicago metropolitan area, the Hispanic population exploded. The six-county area saw an increase of 400,000 in the Latino population, a trend reflected in Riverside, Brookfield and North Riverside.

In 2000, Latinos were 5.5 percent of Riverside’s population, while they made up 8.1 percent of the populations in Brookfield and North Riverside. Ten years later, the percentage of residents claiming Latino descent doubled in Riverside (10.5 percent) and Brookfield (16.2 percent) and tripled in North Riverside (23.8 percent).

Riverside and Brookfield also saw their small Asian populations jump from 2000 to 2010. North Riverside, on the other hand, saw its Asian population fall slightly. In the six-county metro area, the Asian population increased by more than 130,000 people. No other group except for Latinos saw such a dramatic increase in the past 10 years.
