The U.S. labor market has showed signs of continued strength as the nation's companies added some 237,000 jobs in June, Bloomberg said, based on figures from the ADP Research Institute.

The "steady, broad-based growth" that exceeded the business publication's expectations may signal future wage increases and a positive outlook for consumer spending and the economy as a whole. Mark Zandi, chief economist at Moody's Analytics Inc., which produces the figures with ADP, also shared Bloomberg's optimism.

"The U.S. job machine remains in high gear," Zandi said in a statement. "The current robust pace of job growth is double that needed to absorb the growth in the working age population; most encouraging is the healthy rate of job growth among the nation's smallest companies."

Most of the employment growth occurred in the service industry, which created some 225,000 new jobs; goods-producing firms, on the other hand, contributed a net 12,000 positions, CNBC detailed. The construction industry posted strong gains, adding 19,000 jobs, while manufacturing helped create some 7,000 positions in June, according to The Hill.

Small businesses continue to power the labor market, the Wall Street Journal said. Firms employing between 1-and-49 individuals added some 120,000 new workers last month. Medium-size businesses (50-to-499 workers) created 86,000 jobs, while large firms (500-or-more workers) added 32,000 positions.

Zandi mentioned the loss of jobs in the energy sector, which has taken a hit from the sharp drop in oil prices last year, as "the only blemish in the job market," Agence France-Presse noted.

Based on its median forecast of economists, Bloomberg, meanwhile, said it expected the June jobs report issued by the U.S. Department of Labor to show that private businesses have added about 225,000 employees. The business publication also predicted a drop in the unemployment rate to 5.4 percent, which would be the lowest figure since 2008.
