Ohio's population continues to become more diverse, mostly due to growth in the numbers of Asian and Hispanic residents, new U.S. Census estimates show.

The Hispanic population grew in every county in Ohio between the 2010 Census and July 1, 2017, according to the estimates of population based on race and Hispanic origin released Thursday. The state's Hispanic population grew by 86,212 people and bolstered populations in some places that would otherwise be in steeper decline. Asians were the fastest-growing group, growing by 38.1 percent, or 73,871 people, statewide since 2010. That growth occurred mostly in counties that contain Columbus, Cincinnati and Cleveland.

Though both groups grew as a percentage of the state's population, they remain relatively small: Hispanics made up 3.8 percent of the state's population, up from 3.1 percent in 2010 and non-Hispanic Asians made up 2.3 percent of Ohioans, up from 1.7 percent in 2010.

All but 15 counties in Ohio showed declines in the population of non-Hispanic white residents, and Ohio has lost more than 153,000 white residents since 2010, nearly the number of Asian and Hispanic residents the state added. Still, whites continue to be the majority in every county and made up 79.1 percent of the state's residents last year, down from 81.2 percent in 2010.

The population of non-Hispanic black residents grew in 65 of Ohio's 88 counties and they make up 12.5 percent of the state's residents, up from 12.1 percent in 2010. Non-Hispanic people with two or more races gained in every Ohio county and make up 2.1 percent of the state's population, up from 1.7 percent in 2010.

The Census Bureau ascribed most growth in the Hispanic population nationally to births. For Asians, the bureau said growth mostly came from immigration.

The state, and the country, are seeing growth in the population of young Latinos who were born here and are bi-lingual and bi-cultural, said Josue Vicente, executive director of the Ohio Hispanic Coalition.

"That will be the new workforce in the market," Vicente said. "They will bring new skills in the market."

Without Hispanic growth, cities such as Akron would struggle more with stagnation and abandonment, said Madhu Sharma, executive director of the International Institute of Akron, a nonprofit group that welcomes new Americans.

The North Hill area of Akron, where the Hispanic population is concentrated, is the only area of the city with significant growth, she said.

"I feel like a lot of good things are happening in the city of Akron," Sharma said. "You see new businesses coming up and you see community organizations supported."

Asian immigration, at least among Japanese nationals moving here, is being driven by investment by Japanese firms in Ohio-based businesses, said Benjamin Pachter, executive director of the Japan-America Society of Central Ohio. Though the majority of the workers are American citizens, firms such as Honda in central Ohio and Toyota in southwestern Ohio bring in workers, often for several years at a time, he said.

"There is a continuation of growth in investment," Pachter said. "There is also growth in Japanese workers being sent over from Japan to work in these facilities."

The Ohio numbers mirror those of the nation, where the Census estimates the Hispanic population grew 2.1 percent to 58.9 million since 2010, the number of Asians went up 3.1 percent to 22.2 million, the black or African-American population increased 1.2 percent to 47.4 million, and non-Hispanic whites declined by 0.02 percent to 257.4 million.

The new Census estimates also include age data. The median age for the nation was 38 years in 2017, up from 37.2 years in 2010. In Ohio, the median age was higher: 39.4 years in 2017, up from 38.8 years in 2010.

In Ohio, the data show that all but four counties trended older from 2010 to 2017. Wood, Mercer and Hamilton counties showed slight declines in median age. Montgomery County, home to Dayton, remained the same.

Though Stark County's median age rose from 41 to 42 years old.
