The number of job openings in the United States was little changed at 6.7 million on the last business day of April, the Bureau of Labor Statistics reported Tuesday.

The data showed that the job opening rate was 4.3 percent in April while the number of hires was little changed at 5.6 million.

The hiring rate was 3.8 percent with total private and government hiring rates remaining virtually unchanged.

The number of total separations was also little changed at 5.4 million, that is, a 3.6 percent rate.

Hirings and separations occur every month throughout the business cycle. When the number of hires exceeds the number of separations, employment rises, even if the hiring level is steady or declining.

Conversely, when the number of hires is less than the number of separations, employment declines, even if the hiring level is steady or rising.

Over the 12 months ending in April, hires totaled 66.1 million and separations 63.7 million, yielding a net employment gain of 2.4 million.
