According to job site Glassdoor, the annual median base pay in the United States grew 1.7 percent year over year in June 2017 to $51,324. The Glassdoor Local Pay Reports show pay growth remained sluggish, decelerating to 1.7 percent from 2.2 percent revised pay growth recorded last month, marking a five-month slowdown and sharply lower than the 3.1 percent growth pace in January 2017. For the first time in three years, inflation (1.9 percent) outpaced wage growth (1.7 percent YOY) in the U.S. The last time the cost of living was rising faster than wages in the U.S. was July 2014, Glassdoor data shows.

Twenty-five new job titles were added to the Glassdoor Local Pay Reports this month, providing additional insight into wage growth patterns across jobs in retail, health care, technology, labor, manufacturing, and other industries. The monthly reports provide a unique view into the country's wage picture with salary estimates for nearly 85 job titles and year-over-year pay growth trends in the United States. The reports include details on 10 major metros: Atlanta, Boston, Chicago, Houston, Los Angeles, New York City, Philadelphia, San Francisco, Seattle and Washington, D.C.

"Overall, pay growth is slowing in the U.S. This remains a puzzle for economists because unemployment is setting new record lows in many cities. Looking at average U.S. wage growth alone doesn't tell the whole story. Few earn the median U.S. salary, most employees earn a salary relevant to their specific job and city. While we see declining wage growth for jobs where automation is coming, we also see strong pay growth for certain in-demand jobs, as well as sustained high median pay gains for many retail, technology, health care, and professional services jobs," said Dr. Andrew Chamberlain, chief economist of Glassdoor.

Above Average Pay Growth in Online Retail Jobs: Warehouse Associate, Delivery Driver

Reflecting the country's shift toward shopping online for everything from books to groceries, warehouse associates (up 4.9 percent to $41,442) and delivery drivers (up 4.3 percent to $38,660) are in demand, and these jobs experienced above average YOY pay growth in June.

"The growth of the Amazon supply chain, including the recent acquisition of Whole Foods, is no doubt contributing to the increase in demand for warehouse jobs and delivery drivers, leading to the growth in pay for these roles," said Chamberlain.

Recruiter pay continues to rise quickly, up 8.4 percent in June to a median base pay of $51,585. "Companies rely more on recruiters to attract coveted talent as the U.S. reaches full employment, and this puts their skills in high demand," said Chamberlain.

Barista and Restaurant Cook Wages Growing at Faster Pace

Typical minimum wage jobs in the food services industry saw some of the most rapid YOY wage gains in June. Baristas (up 7.7 percent to $24,593) and restaurant cooks (up 7.2 percent to $29,025) saw pay gains in all 10 markets tracked by the reports.

"While baristas and restaurant cooks saw some of the fastest wage gains YOY, they are also among the lowest paid jobs we track. It is likely that recent minimum wage hikes in cities and states across the country have contributed to the growth our reports show for these jobs," said Chamberlain.

Automation Reflected in Shrinking Pay Growth for Some Jobs 

Jobs with the biggest declines in YOY wages included loan officer (down 5.3 percent to $44,306), design engineer (down 3.8 percent to $69,490), operations analyst (down 2.5 percent to $52,412) and financial advisor (down 1.2 percent to $53,522).

"Automation is certainly playing a role in jobs with declining pay. Companies are utilizing new technology, and many tasks which used to require a skilled person no longer do. Banks can share financial advice and process more loan applications online, and product designs and operations analyses are likewise becoming more automated," said Chamberlain.

Pay Growth in Houston Nearly Flat, While San Francisco Wage Growth Gains

In Houston, wage growth was nearly flat this month, and in Atlanta, Washington, D.C., and Philadelphia pay growth lagged far behind the U.S. average. Houston median base pay rose by just 0.5 percent YOY to $54,365. In Atlanta, D.C., and Philadelphia, median base pay rose by 0.9 percent YOY June.
