Congressional District level information by Daily Kos

Description

Some of the most consequential variables to include in MRP are at the district-level. We include one such data for congressional districts. All data is collected by Daily Kos. cd_info_2018 is data on 2018 boundaries, cd_info_2016 uses 2016 boundaries and cd_info_2020 uses 2020 (but with place descriptions currently at 2016).

Usage

cd_info_2018

cd_info_2016

cd_info_2020

elec_NY

Format

Each ⁠cd_info_20**⁠ is a dataframe with the 435 Congressional Districts, one row per cd.

year: The year for the district line. A congressional district's actual geography can change year to year, and significantly so in different redistricting cycles. Lines try to get the contemporaneous district map, so that cd_info_2016 uses 2016 maps and cd_info_2020 uses 2020 maps. However, this work relies on the hard work of assembling precinct results by Daily Kos.
cd: District code. The formatting corresponds to the CCES cumulative coding of cd: a two-letter abbreviation for the state followed by a dash, and the district number padded with zeros to the left to be of length 2. At-large districts like Delaware are given a "-01" for the district number.
presvotes_total: In presidential years, the total number of votes cast for the office of President that year. Taken from Daily Kos estimates from precinct results.
pct_trump, pct_romney, pct_mccain: The two-party voteshare of Republican presidential candidates in that district for the given year. E.g. the pct_mccain data when cd_year == 2018 represents the percent of the vote by McCain in 2008 for that district under 2018 lines. The Trump value is for 2016 for cd_info_2018 and “cd_info_2020⁠but not for 2020 where we use Trump's 2020 vote against Biden and denote as⁠pct_trump16' the 2016 result.
dailykos_name: The unique descriptive name for the district code in 2018 given by Daily Kos. Some edits are made for changing district. See Source for full citation.
largest_place: The largest place in the district code in 2018 given by Daily Kos. Multiple districts may have the largest place.
