Outlook for jobs in science 

The United States Bureau of Labor Statistics (BLS) predicts that careers in life, physical, and social science will grow at a rate of 8 percent between 2020 and 2030 [2]. Careers in biomedical research and environmental protection are expected to be in high demand.  

Health care jobs, which often require a science degree, will also likely be in high demand, according to the BLS. It's expected that the United States will add 2.6 million new health care positions between 2020 and 2030, more than any other industry.  [3
