Guide to datasets compiling election results at levels below the electoral constituency/district (i.e., the level at which seats are distributed). Currently, only Western countries are included, and the time period is typically the last decade or two. Results are reported at varying geographic levels by country, but often at the level of the voting precinct.

Public Opinion & Survey Data Guide

Note: These annotated guides were prepared to help Princeton University students and faculty. While I hope the guides will be of use to everyone, many of the links are to proprietary datasets and resources provided by the Princeton University Library and restricted to members of the Princeton University community.
