The Data Scientist Career Outlook

According to the data recently provided by the U.S. Bureau of Labor Statistics, data scientist employment is projected to increase 35 percent between 2022 and 2032, a rate that is considerably faster than the average for other occupations.

This growth figure translates into about 17,700 new openings for data scientists annually, on average, throughout the decade. Many of these openings are expected to come from the need to replace workers who either left the labor force (e.g., retired) or who decide to move on to different occupations.

According to Indeed.com, data scientists working in the United States may earn an annual average of $125,254, with figures as high as $189,359.

So, the future looks bright for data scientists. As long as our society relies on data, there will be a need for data scientists. Spoiler alert: modern society will always rely on data!
