Planning on entering the job market or switching vocations in the next five years? CareerBuilder has just released its list of the fastest-growing occupations through 2021.

While overall employment is expected to rise 4.6 percent in that period, with 7.2 million jobs available in total, a few specific avenues may see as much as a 32 percent increase. Among them:

1. TRANSLATION SERVICES

Jobs that shrink language gaps are expected to see a 28 percent increase in the next five years, with over 10,000 new positions needing talented and fluent communicators for both written (translation) and verbal (interpretation) assignments. While plenty of business opportunities will be available, you're likely to see slots for legal proceedings—including witness testimony—and hospitals.

2. PHYSICAL, OCCUPATIONAL, AND SPEECH THERAPISTS

Over 92,000 new jobs are expected to open up for positions that help those recovering from injury or illness, a 25 percent increase from 2016. One possible reason: the increasing population of seniors.

3. NAIL SALONS

CareerBuilder forecasts a 19 percent increase in nail technicians—a license is required in most states. Naturally, the job involves a lot of sitting.

4. WAREHOUSE CLUBS

Arena-sized mega markets continue to grow, with over a quarter-million new jobs expected to open for an increase of 17 percent.

5. TELEMARKETERS

Good news for job hunters, bad news for people who can’t seem to get off call lists: Call centers could see as many as 97,000 new headset-sporting employees joining the half-million individuals already in the workforce. Florida, Texas, and California have higher concentrations of speed-dialers than any other state.
