The number of computer science positions available in the U.S. continues to rise, with more than 5.3 million computer science and engineering jobs listed as “critical” by job seekers nationwide.

The number of U.s. computer science workers has more than doubled over the last 10 years to more than 21 million, according to the latest U.K. Computer Society report, the most recent survey of U,S.

The Computer Science Department at the University of Waterloo, Canada, and the University at Buffalo, New York, released their most recent annual report on computer science employment, which shows computer science job vacancies are projected to increase to about 4.5 million jobs by 2020.

The total number of vacancies in computer science was almost 6.1 million at the end of December, according the report.

The report says computer science has been an increasingly important job for workers in the last decade.

Computer science positions are often held by senior managers and computer science graduates, who are increasingly needed to manage complex systems and make decisions on complex data.

Computer scientists in the United States were ranked as the 13th most important job in the country in 2012.

About 16% of computer scientists are in STEM fields, or the study of computer technology and mathematics.
