The hottest industries for jobs are always changing. If you're looking for work in 2016, take a look at our list below. Certain areas of employment are more promising than others.

Tracey Wilen, author of "Employed for Life: 21st-Century Career Trends," helped us compile a list of five sectors that are buzzing as we enter the new year.

1. Senior services

According to Wilen, tens of thousands of people each day are turning 65 years old, opening up plenty of employment opportunities in a number of fields.

Wellness is an obvious biggie. There's a potential employment gap of about 33,000 next year for jobs such as physical therapists, registered nurses and home health aides.

Meanwhile, with demand at an all-time high for senior housing, there should be no shortage of positions at retirement communities and assisted living facilities.

The elderly are also predicted to be a driving force in job opportunities related to travel. The market of retirement travelers will grow by 36 percent over the next 10 years, AARP estimates.

"All of the jobs connected to travel...hotels, airlines, buses, trains, restaurants and tours, can all benefit from this segment," Wilen said.

By the year 2030, according to the Census Bureau, 20 percent of the U.S. population will be 65 and older.

2. Security

Sadly, the world we live in today opens the door to several security employment opportunities in order to protect your identity, transportation systems, internet connection and overall safety.

Wilen said widespread hacks of major companies such as Target and Home Depot have created a need for those who can combat such attacks.

At the same time, counterterrorism jobs such as undercover agents and cryptographers are emerging, along with others that require minimal education.

The Freedonia Group suggested the market for security guard and patrol services will increase by 2 percent in 2016 nationwide.

3. Blue collar skills

A recent USA TODAY analysis estimated an additional 2.5 million middle-skill jobs by 2017.

Wilen said many of these jobs can pay quite well (over $50K), from electricians and refinery workers to commercial divers and locomotive engineers.

An article on MPRnews.com advised millennials to look to the trades for jobs. Although unemployment is higher for those without a college degree, Wilen said, there is plenty of opportunity in the trades (plumbers, carpenters, air conditioning installers).

4. Be your own boss

Apps and sites such as Airbnb, Etsy and Uber are allowing people to work for themselves and maintain a balanced lifestyle.

Franchising, according to Wilen, is the perfect choice for folks who want to have their own business but can't get an idea off the ground, as long as the price is right.

According to the International Franchising Association in early 2015, more than 12,000 franchises were expected to open by the end of this year, adding 247,000 jobs.

5. Trendy technology

While this may pave the way to a world less dependent on human labor, it's a promising field for us right now.

"I see artificial intelligence, immersive technology and drones taking off," Wilen said. "I think all of these areas are creating demand and opportunities for people, whether it's 3-D artists and analysts, computer scientists or virtual reality experts."

The drone market, according to the Association for Unmanned Vehicle Systems International, will create more than 100,000 jobs nationwide over the next 10 years.

Amazon already has a webpage devoted to its feature known as Prime Air, aiming to eventually get packages to customers within 30 minutes, using small unmanned aerial vehicles.
