Standardized Records from the Demographic Survey of Unsheltered Individuals
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.
Both files have some additional processing
