Documentation

The Los Angeles Homeless Services Authority (LAHSA) conducts annual in-person surveys of the unsheltered homeless population in Los Angeles. This data package includes the standardized versions of the annual survey data for 2011 through 2017, combined into a single file (combined_survey) and another multi year file that was produced by UCLA, which includes only the common columns from the multi-year files. (multiyear_survey)

The combined_survey includes all of the columns from all of the years, although many columns only exist for one year. The result is that many of variables are null for one or more of the survey years.

The source for the multiyear_survey file was produced by UCLA and includes only a subset of the columns available in combined_survey, but the variables have many more non-null values.

The best way to compare these files is to look at the EDA notebooks for the files, and in particular, the Null map at the end of the notebook.

Processing

Both files have some additional processing

• ‘NA’ values are converted to blank cells
• A new sex column which codes the genders Male as ‘M’, Female as ‘F’, and all others as ‘U’
• A new raceeth variable for census race and ethnicity categories with values for black, white, asian, aian, aian, nhopi, hisp and other, based on keywords in the Race_Full variable.
• Strip trailing spaces from Race_Full
• A new geoid variable that holds the census tract variable converted to a format Census geoid.
• A new year variable that holds an integer version of the `Survey_Year`` variable
