About SPP Databases
Databases’ Structure
The Subnational Politics Project (SPP) is made up of different databases. Each database employs a country–state–year structure, with observations at the subnational unit level for each electoral year. Each observation represents a subnational unit (province/state) in a given year.
Variable Information
The databases in the Subnational Politics Project divide variables into the following types:
- Identifier Variables: Data identifying country names and codes, state names and codes, region names, and time periods.
- Executive Branch Variables: Data on national and subnational executive branches, such as length of term, incumbent party, cumulative years of president/governor in office, etc.
- Electoral Variables: Data on subnational executive and subnational legislative elections, including legislatures’ composition.
- Indices: Data generated by adding and combining variables, or creating cumulative scales.
ABOUT
About SPP
The Subnational Politics Project (SPP) is a collaborative initiative dedicated to compiling, generating, and disseminating systematic, transparent, and publicly accessible data on subnational political institutions, processes, and electoral outcomes across Latin America.
The SPP’s central goal is to build a comprehensive and standardized data infrastructure that enables both detailed within-country analysis and robust cross-national comparisons of subnational political dynamics.
By providing consistent, high-quality, and spatially disaggregated longitudinal data, the SPP seeks to advance scholarly and policy-oriented research on the political foundations and consequences of territorial inequality in Latin America.
This data infrastructure will support empirical work on a wide range of topics, including federalism, decentralization, subnational democracy and authoritarianism, party competition, electoral accountability, territorial governance, among others.
