Overall employment in the U.S. economy is projected to increase 6.5 percent during the 2014–24 decade, adding about 9.8 million new jobs. The most new jobs added and fastest job growth will occur in healthcare practitioners and technical occupations and healthcare support occupations. Projected changes to demographics as the population ages will drive the expected growth in the healthcare occupational groups. Production occupations and farming, fishing, and forestry occupations are the only major occupational groups projected to decline.
U.S. employment is projected to increase 6.5 percent during the 2014–24 decade, from 150.5 million jobs in 2014 to 160.3 million jobs in 2024. The U.S. Bureau of Labor Statistics (BLS) Employment Projections program releases projections for 819 detailed occupations. Employment in 602 occupations is projected to increase, while employment in 217 occupations is projected to decline.
Healthcare support occupations and healthcare practitioners and technical occupations are projected to be the two fastest growing occupational groups, adding a combined 2.3 million jobs, about 1 in 4 new jobs. Figure 1 shows the share of total employment for these two groups in 2014 and projected 2024. The combined share of employment for these two groups is projected to increase from 8.3 percent of all jobs in 2014 to 9.2 percent of all jobs in 2024.

Answer:
When groups are not equivalent, researchers can look at changes from pretest to posttest scores.
Explanation:
A nonequivalent control group
This is simply regarded as a control group that is set on certain previous (preexisting) descriptions or characteristics that is almost the same or similar to those observed in a treatment group and participants are not randomly assigned. it is said that in a quasi experiment, a dependent variable measured in a treatment group is compared to that in the nonequivalent control group.
A nonequivalent control group pretest-posttest design
In this type of design, it is said that the dependent variable is scored or measured in one group of participants before the pretest is made and also after the posttest, a treatment and that same dependent variable is also measured at pretest and posttest in another nonequivalent control group that does not receive the treatment. Here, the groups are not usually equivalent.
Advantages and disadvantages of the nonequivalent control group pretest-posttest design
Advantages
1. it is often used to rate or compare scores before and after a treatment in a group that receives the treatment and in a group that does not.
Disadvantages
1. it is prone to the threat of selection differences.
