Two-thirds of manufacturers in New York State and service firms in the metropolitan region expect to raise employee salaries this year, according to two surveys.

The Federal Reserve Bank of New York said wages for the typical factory worker, excluding medical and retirement benefits, would increase 2.3 percent in 2016, on average, based on responses to its poll of about 100 plants across the state. The bank conducted the poll earlier this month.

About a year ago, factories in a similar New York Fed survey estimated they would boost wages 3.1 percent in 2015, on average.

In a separate poll, about 100 retailers and other service firms predicted their typical worker would be paid 3.1 percent more, on average, in 2016, excluding benefits. That’s up from the 2.7 percent raise projected for 2015 in a poll last April.

The service firms polled are on Long Island, in New York City and its northern suburbs.

The New York Fed said this week that “no respondent projected a decrease” in workers’ pay in the surveys this month.

Companies were also asked if they expected their starting salaries for new workers to change in 2016, compared to last year. “Forty-five percent of service firms and 54 percent of manufacturers projected an increase,” the bank said.

Both plants and service firms have added workers in the past 12 months, though the median number of four people among plants is down one person from the April 2015 polls. Among service firms, the median added was five people, unchanged from a year ago.

“When asked how long, on average, it had taken to fill job openings . . . the median manufacturing respondent said 30 days, while the median service-sector respondent indicated 40 days,” the New York Fed said.

More than three in 10 plants and service firms said it took longer to fill job vacancies than in 2014. “Only a handful of respondents . . . said the duration had declined” year over year, the bank reported.
