Voters in San Francisco next week will decide whether to aggressively ramp up funding to combat homelessness. A tax on large businesses known as Proposition C would raise up to $300 million annually.

It’s similar to the $1.2 billion bond that Los Angeles voters approved two years ago to build thousands of homes for the chronically homeless.

Will these measures work? Much depends on how quickly and how well they are carried out, and what happens to the economy.

Dennis Culhane, an expert on homelessness at the University of Pennsylvania, says there is also a much more unappreciated factor: demographics.
