IPUMS NHGIS Time Series Metadata
An NHGIS time series table links together comparable statistics from multiple datasets into one table. An in-depth introduction and a full catalog of NHGIS time series tables are availble on the NHGIS website.
Below we provide examples in curl showing how to work with our API to access metadata about NHGIS time series tables.
If you are an R or Python user, please note that we also provide language-native client libraries to make it easier to work with the IPUMS API using those languages.
Get High-Level Metadata for Time Series Tables
This API call will return a list of all available time series tables. The entry for each time series table includes metadata for the table’s description, geographic levels, year availability, and geographic integration. The unique identifier for each time series table is in the name field. This is needed for retrieving details about a single time series table (see next section).
curl -X GET \
"https://api.ipums.org/metadata/time_series_tables?collection=nhgis&version=2&pageSize=10" \
-H "Authorization: $MY_KEY"

Get Detailed Metadata for a Single Time Series Table
This API call will return the details of a single time series table, A00 in this example. The details repeat a lot of the information from the time series table call above, but also contain additional information on the individual time series contained within the table.
curl -X GET \
"https://api.ipums.org/metadata/time_series_tables/A00?collection=nhgis&version=2" \
-H "Authorization: $MY_KEY" | jq
