Robots working in the United States manufacturing industry have tripled over the last couple of decades while in other parts of the world they have doubled, according to a new report.

The report, which was conducted by the Federal Reserve Bank of St. Louis, discovered that automation in the U.S. has increased to 1.8 robots for every 1,000 human workers. This estimate is as of 2017, and it is up from the 0.5 robots for every 1,000 human workers estimated 22 years prior.

"France, and the average of the countries Spain, the U.K. and Sweden were ahead of the U.S. in the late 1990s and early 2000s but in the last decade it seems the U.S. has overtaken these countries," the report found.

The report also suggests that the industry with the highest prevalence of robots is the auto industry, where France is leading the way with 148 robots for every 1,000 human workers. Meanwhile, in the U.S., the auto industry number is 136 robots for every 1,000 human workers, followed by Italy and Germany, where it is estimated that there are 120 robots for every 1,000 human workers in those auto industries.

The report’s findings are far from surprising as each day seems to bring news about unexpected industries welcoming automation. For instance, it is estimated that more than 7,000 robots will be working in the construction industry by 2025. Similarly, robots are also taking on security roles in the defense industry worldwide as well as roles in the food and beverage industry, to name just a few.
