Average U.S. weekly wages increased 3.9 percent in the fourth quarter of 2017, reaching a total of $1,109 per week, according to a recent report from the U.S. Bureau of Labor Statistics (BLS).

Average weekly wages increased over the year in all of the 10 largest U.S. counties, the bureau added.

However, wages grew more rapidly than the national average in certain parts of the country, according to the report. 

The cause for wage increases varied depending on location, according to BLS. For example, the financial industry had the biggest impact on wages in New York, according to BLS data, with average weekly wages increasing by $1,032, or 22.4 percent, over the year in New York's financial sector.

The county of Harris, Texas, had the smallest percentage gain in average weekly wages among the 10 largest counties (2.4 percent). Within Harris, trade, transportation and utilities had the largest impact on the county’s average weekly wage growth with an increase of $49 (4.3 percent) over the year.

These counties, in ascending order, had the biggest increases in weekly wages:
