After all, getting the most candy in the least amount of time on Oct. 31 requires that you go where the people are packed in the tightest. But density isn’t the only factor that makes for a good Halloween experience if you asks the economists at real-estate data firm Zillow.

Using home values, single-family home density, crime rates, and the share of the population under 10 years old, they compiled an index to determine the best cities in the U.S. for candy canvassing. “This data combines to give us the safest cities to trick or treat, where trick-or-treaters can get the best candy, in the least amount of time,” Zillow says.

The density of single-family homes in Philadelphia rocketed the City of Brotherly Love to the top of the list, followed by San Jose, San Francisco, Milwaukee, and Los Angeles. Check out the rest of the list below.
