In 1950, the population of Minneapolis was 521,718. It was the 17th largest city in the United States, with more people than Dallas, Denver, Miami or Seattle.

U.S. Census Bureau estimates for 2012 ranked Minneapolis as the nation’s 47th largest city, with 392,880 residents. Dallas, Denver, Miami and Seattle all have bigger populations.

Does it matter?

Mayor R.T. Rybak thinks so. In his August budget speech, he said Minneapolis should aim for a population of 500,000 by 2025, an increase from the 450,000 goal he set in his State of the City speech in April.

At a forum last week on urban design and development, several candidates who are vying to succeed Rybak also endorsed the 500,000-by-2025 goal.

The mayor said in his budget speech that the half-million benchmark is about more than bragging rights. The larger the population, “the more people there are to support strong schools, shopping districts, restaurants, art groups” and other amenities, he said.

“Equally importantly,” he said, “more people living in Minneapolis means that more of us share the costs of running a city: When we split the costs of police, firefighters, roads and water with more people, each of us pays less.”

Can it be done?

That translates into a reduction in property tax burdens. Sounds good, doesn’t it? But how realistic is Rybak’s goal?

In September, the Metropolitan Council released preliminary population projections for 2040. It figured Minneapolis’ population 27 years from now will reach 487,700.

If the economy stays strong and Minneapolis continues to grow, says Metropolitan Council demographer Todd Graham, the city could add 20,000 housing units and be home to 450,000 people by 2025.

“Economic growth is the main driver,” he says. “It’s the main pull and magnet for attracting people here from other parts of the country and other parts of the world.”

The city has experienced a strong rebound from the Great Recession and has experienced “substantial growth” of more than 10,000 residents since the 2010 Census, Graham says.

A building boom in downtown apartments and falling rental vacancy rates are feeding that gain, he says, but those factors can’t be counted on to be permanent trends.

For any city that wants to grow, Graham says, “the biggest challenges are can you find the land, can you build and can you find a market demand for what’s being built.”

At last week’s mayoral candidate forum, there was general agreement that Minneapolis’ expanding transit options, including light rail and a proposed streetcar, will attract newcomers who want to live in the city but don’t want to drive — and draw developers who will build housing along those transportation lines.

“We think we are seeing a shift in real-estate preferences by people looking for housing,” Graham says. More younger people and seniors want “central locations and accessibility to work and things to do.”

Ironically, changes in transportation fueled Minneapolis’ population drop after it peaked in the 1950 census. The metro area’s two main conduits, Interstate 35 and Interstate 94, were built in the 1960s, helping to lure people from the city to the suburbs.

Analysis of census reports by the Population Reference Bureau shows that the United State’s biggest cities are experiencing growth rates that exceed the national average.

Biggest cities

The 10 largest cities are New York, Los Angeles, Chicago, Houston, Philadelphia, Phoenix, San Antonio, San Diego, Dallas and San Jose. They represent 8 percent of the country’s total population. After net population declines between 2003 and 2005, they were responsible for more than 11 percent of U.S. population growth from 2011-2012.

Giant jumps in population are possible, but often are a result of singular circumstances. New Orleans’ population has grown 28 percent since 2007 to 369,250. That’s about 81 percent of its population before the city was decimated by flooding in the aftermath of Hurricane Katrina in 2005.

Detroit, on the other hand, is the poster child for population loss. In 1950, it was the nation’s fifth largest with city 1.8 million residents. Census estimates for 2012 put the population now at less than half that number — 701,475.

William Frey, a demographer and senior fellow at the Brookings Institution in Washington, D.C., says Minneapolis’ growth rate rose from an annual average of 0.4 percent from 1990-2000 to zero growth from 2000-2010. The rate increased 1.3 percebnt between 2010 and 2011 and 1.2 percent from 2011 to 2012, he says.

“Minneapolis would have to sustain a 2-plus percent annual growth rate to come close to reaching 500,000 in 10 years,” Frey says. “Right now, the only cities doing that are in rapidly growing Sunbelt cities like Austin or Charlotte, and they are also located inside rapidly growing metro areas.”

Still, Frey says Minneapolis has clearly rebounded from a period of declining population and has the potential for further increases.

“The growth would be especially useful if it included a mix of professionals, retiring boomers with disposable incomes, but also young people willing to raise their children in the city – leading to stable neighborhoods,” he says.

St. Paul’s estimated 2012 population was 290,770, up from 285,068 in the 2010 census. The Metropolitan Council projects the capital city will have 338,900 residents by 2040.

Graham sees reasons for Minneapolis’ optimism. “We’re now in the fourth year of employment growth,” he says. After the city issued 1,500 to 1,700 permits for housing units each year from 2002 to 2006, there were 3,346 in 2012 and the city is on a similar pace so far this year.
