Visitors to Memorial Park on an early weekday afternoon probably have to stop and wonder where all these people are coming from. Don’t they have work to do?

Maybe they do, but on their own schedules. Fiverr, a marketplace for connecting freelancers and new clients, released its fifth annual Freelance Economic Impact Report, ranking Houston as the tenth fastest-growing city for freelancers.

According to the report, some 144,000 workers in Houston made $6.6 billion. That means the Bayou City led Texas with around $46,000 for per capita income.

Elsewhere in Texas, Austin came in as the fourth fastest-growing city for freelancers. The city's 77,262-person independent workforce earned $3.4 billion in 2021. In Dallas, which came in at No. 8, some 177, 500 workers made $7.6 billion.

Joining Houston, Austin, and Dallas in the top 10 were:

1. Orlando, Florida
2. Nashville, Tennessee
3. Miami, Florida
5. Tampa, Florida
6. Las Vegas, Nevada
7. Charlotte, North Carolina
9. Portland, Oregon

Although on the surface the report focuses on geography, it collected data that shows eight out of 10 freelancers believe they can live anywhere and work anytime. However, fewer than half reported that it was “a primary factor” in becoming freelancers, and a third said that work was “a primary influence” in their choice of location.

Most important, 70 percent of respondents said they were “highly satisfied” with working independently.

Houston flourishes as one of the nation's top hubs for freelancers

Self-employment Surge

It's no wonder coworking is taking off in Houston. A new study shows the community of skilled freelance workers in Houston ranks as one of the biggest in Texas — and the United States.

The study, commissioned by freelance marketplace Fiverr and conducted by market research firm Rockbridge Associates, indicates Houston was home to an estimated 117,260 skilled freelancers who generated more than $4.1 billion in revenue in 2018, just slightly less than the financial haul in 2017.

Houston ranked second statewide and 11th in the U.S. among major metro areas for the size of the skilled-freelancer workforce and for the amount of revenue produced, according to the study. Between 2017 and 2018, Houston's pool of skilled freelancers grew 2.5 percent.

From 2011 to 2016, according to the study, Houston's community of skilled freelancers increased 7.7 percent, while revenue declined slightly by 7.8 percent. The Fiverr study places skilled freelancers in three buckets: creative, technical, and professional. These freelancers include attorneys, graphic designers, musicians, software engineers, accountants, and consultants. Any self-employed person whose work requires "specific skills and abilities" was counted in the study; excluded were folks like Uber and Lyft drivers.

"Highly skilled freelancers are an understudied and often overlooked segment of the workforce," Brent Messenger, Fiverr's vice president of public policy and community, says in a release. "By analyzing the data around these … workers, we're able to get a clear picture of the types of jobs they're doing, the amount of revenue they're generating, and the cities in which they're having the most impact."

DFW ranked first in Texas and seventh nationally in the study. In 2018, DFW was home to an estimated 154,617 skilled freelancers who generated nearly $6.38 billion in revenue in 2018, up 5.4 percent from the previous year.

While DFW dominates Texas in terms of freelance population and revenue, Austin boasts the fastest-growing freelance scene.

In 2018, the estimated 67,044 skilled freelancers in the Austin metro area produced nearly $2.7 billion in revenue, up 7.5 percent from 2017, the study says. During the one-year period, Austin's pool of skilled freelancers grew 7.4 percent. The study pegged Austin at No. 18 nationally for the size of the population and revenue of skilled freelancers.

From 2011 to 2016, according to the study, Austin's community of skilled freelancers shot up by 26 percent, with revenue climbing 31 percent. The study identified Austin and Nashville as the country's two fastest-growing hubs for skilled freelancers.

A recent study by commercial real estate website CommercialCafé found that Austin, Dallas, and Houston ranked among the most affordable U.S. cities for freelancers. Meanwhile, personal finance website NerdWallet in 2016 ranked Austin as the best place in the U.S. for freelancers, with Dallas at No. 3, Fort Worth at No. 8, and Houston at No. 15.

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”
