Introduction to Homeless Data Analysis

In preparation for the Data Science for Non Profits meeting tomorrow night (Wednesday, 9 Oct), I’ve created a Google Colab notebook demonstrating how to access the homeless sleeper dataset and compare the distribution of homeless sleepers to crime, pedestrians and businesses. The main output is this chart ( click to expand).

Downtown Homeless Data Released

After 8 months of hard work form many volunteers and staff, we’re releasing the first version of the Downtown Homelessness Dataset. This dataset has about 41,900 observations of homeless sleepers on 287 blocks in Downtown San Diego, over 62 months.

The dataset is part of our Homelessness Collection. If you’d like to learn how to work on this dataset and the others in the collection, join us for a working session at the next meetup for Data Science for Non Profits, Wednesday 9 October.

Homelessness Data Conversion

The San Diego Data Library is building a detailed data set about Downtown homelessness using 5 years of hand-marked paper maps. The conversion process is human-powered, and we need you help to finish the conversion. When we are finished, we will have a very valuable data for doing detailed analysis of the relationship between unsheltered homeless people and the downtown environment, exploring factors such as restrooms, vacant lots, and the presence of services.

Computer Vision For Greater Good!

Use your Computer Vision skills to tackle homelessness.

The Data Library is currently running a data project to convert 5 years of monthly homelessness person locations from scanned paper maps to a geographic dataset. The bulk of the work involves volunteers manually digitizing 350 scanned paper maps in two jobs, but we have enough data to build a computer vision solution.

If you have skills, or motivated interest, in programming OpenCV in Python, you can put your talents to service for humanity, by working on the computer vision portion of this project.

Downtown Homelessness Dataset Progress

Over the summer we’ve been working on a project to digitize maps of homeless person counts that have been collected over the last 5 years by the Downtown San Diego Partnership. We now have partial results for three neighborhoods, with data positions shown in the map below.

We expect to have the dataset complete in the next few weeks, and after some additional quality assurance, it will be ready for analysis. If you are researcher, part-time analysts, or concerned citizen who wants to use a unique datasets of 5 years of monthly position reports for homeless individuals, let us know.

Exploring San Diego Homelessness

Over the past few months, the Data Library has been involved in several projects to study homelessness in San Diego. The main projects have been:

Last Spring, we got the first portion of the Downtown homelessness data converted with the help of Kearney High students, and this fall, we’ll be finishing the rest of the data conversion and doing data analysis. If you’d like to participate, you can contact me, or watch for our next project meetup.
