Rapid growth is also expected among computer systems analysts as technology advances and organizations place more emphasis on network applications and maximizing the efficiency of their computer systems. On the other hand, automation, the expanding use of computers, and developments in computer software will result in limited growth or declining employment among many clerical workers, machine operators, and assemblers. The projected-year matrix incorporates these expected changes. Data on self-employed workers in each occupation come from the Current Population Survey. Self-employed workers were projected separately.
