We exploit the US census data, the Florida voting registration data, and the Wikipedia data collected by Skiena and colleagues, to predict race and ethnicity based on first and last name or just the last name. The granularity at which we predict the race depends on the dataset. For instance, Skiena et al.' Wikipedia data is at the ethnic group level, while the census data we use in the model (the raw data has additional categories of Native Americans and Bi-racial) merely categorizes between Non-Hispanic Whites, Non-Hispanic Blacks, Asians, and Hispanics.

If you picked a person at random with the last name 'Smith' in the US in 2010 and asked us to guess this person's race (as measured by the census), the best guess would be based on what is available from the aggregated Census file. It is the Bayes Optimal Solution. So what good are last-name-only predictive models for? A few things---if you want to impute race and ethnicity for last names that are not in the census file, infer the race and ethnicity in different years than when the census was conducted (if some assumptions hold), infer the race of people in different countries (if some assumptions hold), etc. The biggest benefit comes in cases where both the first name and last name are known.
We strongly recommend installing ethnicolor inside a Python virtual environment
(see venv documentation <https://docs.python.org/3/library/venv.html#creating-virtual-environments>__)
::
pip install ethnicolr
Or
::
conda install -c soodoku ethnicolr
Notes:
To see the available command line options for any function, please type in
<function-name> --help
::
usage: census_ln [-h] [-y {2000,2010}] [-o OUTPUT] -l LAST input
Appends Census columns by last name
positional arguments: input Input file
optional arguments: -h, --help show this help message and exit -y {2000,2010}, --year {2000,2010} Year of Census data (default=2000) -o OUTPUT, --output OUTPUT Output file with Census data columns -l LAST, --last LAST Name of the column containing the last name
To append census data from 2010 to a file with column header in the first row <ethnicolr/data/input-with-header.csv>__, specify the column name carrying last names using the -l option, keeping the rest the same:
::
census_ln -y 2010 -o output-census2010.csv -l last_name input-with-header.csv
To predict race/ethnicity using Wikipedia full name model <ethnicolr/models/ethnicolr_keras_lstm_wiki_name.ipynb>__, specify the column name of last name and first name by using -l and -f flags respectively.
::
pred_wiki_name -o output-wiki-pred-race.csv -l last_name -f first_name input-with-header.csv
We expose 6 functions, each of which either takes a pandas DataFrame or a CSV.
census_ln(df, lname_col, year=2000)
What it does:
census file <ethnicolr/data/census>__, it appends
relevant data of what probability the name provided is of a certain race/ethnicity+------------+--------------------------------------------------------------------------------------------------------------------------+ | Parameters | | +============+==========================================================================================================================+ | | df : {DataFrame, csv} Pandas dataframe of CSV file contains the names of the individual to be inferred | +------------+--------------------------------------------------------------------------------------------------------------------------+ | | lname_col : {string} name of the column containing the last name | +------------+--------------------------------------------------------------------------------------------------------------------------+ | | Year : {2000, 2010}, default=2000 year of census to use | +------------+--------------------------------------------------------------------------------------------------------------------------+
Output: Appends the following columns to the pandas DataFrame or CSV:
pctwhite, pctblack, pctapi, pctaian, pct2prace, pcthispanic.
See here <https://github.com/appeler/ethnicolr/blob/master/ethnicolr/data/census/census_2000.pdf>__
