More people, earning more money, are flocking to downtown L.A.

More people are flocking to downtown Los Angeles — and they have more money to spend, downtown advocates declared as they unveiled the results of a new study.

“We have more people. They’re making more money. They are more educated. And they are demanding more,” said Carol Schatz, president and chief executive of the Downtown Center Business Improvement District.

Schatz based her comments on an online survey promoted through community newspaper ads, postcards and door hangers. It drew responses from more than 8,800 people, including more than 3,700 residents. The group cautioned the study was not a “census,” but a sampling of “likely consumers.”

It found that the median household income of downtown residents had risen by 10% since its last survey two years ago, and that downtowners were also increasingly educated.

The Downtown Center Business Investment District, funded by special taxes in the downtown area, hopes the results spur more investment in the urban core. People who live, work or visit downtown said they were especially interested in a Trader Joe’s or new department stores such as Nordstrom in the area, the survey found. A Whole Foods is already on the way.

But the changes reshaping the city center have also raised worries about whether poorer residents will be served by a gentrified downtown.

“Low-income and middle-income people are also consumers,” said Becky Dennison, co-director of the Los Angeles Community Action Network, an advocacy group for people in poverty. “Everybody needs to be taken into account when looking at the future.”

The survey was released to reporters in a bright 9th Street loft owned by architect Simon Ha and his wife, Nikki Olson-Ha.

When the Has moved downtown six years ago, friends and family asked whether it was safe and where they would get groceries, Ha said. Now, people who hear they live downtown ask about new restaurants and how the neighborhood has changed, he said.
