Zillow property-level data panel for select California cities – before and after 2020

Codebooks for analyzing property (house, condo, flat, etc.) listing data
for each of the 10 select regions in the bay area megaregion of
California, USA (SAN JOSE, MODESTO, FRESNO, TURLOCK, LIVINGSTON, ATWATER,
MERCED, MADERA, MARIPOSA, OAKHURST) were obtained from Zillow Inc. on a
monthly basis between March 2018 and May 2019 (denoted as the period
before 2020) and May 2020 and September 2021 (after 2020). Combined, the
total number of observations (unique listed properties) is N =
57,414. For each month, we obtained a set of unique listing
identifiers (ZPID) by manually scanning across the entire Zillow.com
directory for a given region and property type (“For Sale” and
“Rent”). Read the enclosed document
DataDryad_DataDescription_Petersen_Zillow.pdf for a description of the
data and output of provided supporting code. Contact the corresponding
author for the raw property-level data files, which are anonymized
[property address and property identifier (ZPID) fields].
