Downtown Los Angeles is in the midst of a renaissance. (Partly because I live there, but I can't claim all the credit.) Amidst the high-rises and cultural institutions, residential building is booming, bringing restaurants and nightlife along with it. But the vibrant core of Downtown is just a few blocks from the epicenter of homelessness in LA: Skid Row. This compact area (official six square blocks) is a magnet for poverty and dispossession, and intentionally so: the city has concentrated services for the homeless near Skid Row, in an attempt to provide relatively easy access for the city's itinerant population. But the neighborhood is by no means a pretty sight: the vision of small tents and ratty cardboard boxes stretching along the streets is an indelible one. And reports continue of local hospitals and mental-health clinics simply giving up on their worst cases and dumping them on Skid Row to fend for themselves. Ideally, you don't want to contain homelessness in a tiny area, you want to eradicate it completely. (The condition, not the people who suffer from it.) One step toward that goal is a better understanding of actual conditions in the region: who the homeless are, how many of them are on the streets, how they live and move through the city. Eric Richardson, who writes the excellent blogdowntown covering everything about Downtown LA, as part of his day job at Cartifact has been working to map Skid Row's homeless population. (Cartifact is also responsible for an interesting interactive map of Downtown.)
It's an impressive project, described here, and the most recent update has just come out. The data come from regular counts undertaken by the LAPD; systematic uncertainties will, of course, be as much of an issue here as in any data-collecting process. By clicking on the lower left corner, you can see the maps change as a function of time, or run through an animation of all the maps for the last several months. The good news is that the most recent count is the lowest yet; this is much more likely to represent a seasonal fluctuation than a long-term trend, but it's still heartening to see.
