Data Sources

Every figure on Maine Political Data originates in a public record. This page identifies those records, the institutions that publish or hold them, and the general manner in which they were compiled into the site’s database.

The sources below are arranged by subject rather than by the page on which their data appear, because a single source often informs several parts of the site. Where a record survives in more than one form — a printed report and a later digital file, or a government web page and its archived copy — each form actually consulted is listed. Citations give the publishing office, the title of the record as that office styles it, the period covered and, where applicable, the repository through which it was obtained.

Each section closes with a note on how the data were treated in compilation. Those notes describe our practice in general terms; the record of every individual adjustment is retained in the project’s database and is available on request.

Voter Registration & Party Enrollment

The following records were used in the registration totals, party-enrollment figures, maps and time series presented on the Voter Registration pages and in the registration panels of every place page.

Note on compilation

These records were used to populate the Maine Political Data registration database. Each report was reconciled town by town against its own printed county totals, and the county totals against the printed state totals. In a small number of instances we identified typographical errors or errors of computation in the original reports; where the correct value could be established with confidence from the report’s own totals or from adjacent reports, the figure was corrected, and where it could not, the entry was left blank. Municipalities omitted from a report are carried forward from the preceding report, and municipalities the Secretary of State reported in combination are apportioned from neighboring reports. For 1954–1970, when the Secretary of State did not report unenrolled voters, the unenrolled figure is derived from the difference between total registration and party enrollment and should be regarded as approximate. Reports from 2007 forward distinguish active from inactive voters; earlier reports do not state voter status. For these reasons, certain figures on this site may differ slightly from those printed in the sources above, and every such figure is marked in the place detail where it appears.

Note on compilation

These records were used to populate the Maine Political Data election-results database. Wherever a source prints its own totals, the sum of our municipal figures was checked against them candidate by candidate; where it does not, statewide sums were checked against the certified results. Recount results are used where printed, as they are the final certified figures. Handwritten corrections that appear on the scanned historical returns were applied unless other evidence contradicted them. In a small number of instances we identified typographical errors, figures entered under the wrong contest, or records duplicated across files, and adjusted them; where a source’s printed total disagrees with the sum of its own municipal figures, the municipal figures are retained. Ranked-choice contests are reported by first choices only. Candidate names have been standardized to a single spelling for each person and party labels retained as printed. Historical returns drawn from scanned records were transcribed by hand and are presented only after reconciliation. For these reasons, certain figures on this site may differ slightly from those printed in the sources above.

Absentee Voting

The following record was used in the figures on absentee ballot requests, returns and rejections by municipality and party.

Note on compilation

Party affiliation is recorded only where a primary source states it; where none does, a member is shown as “party not recorded” rather than assigned a party by inference. Chamber totals before 1872 are those published by Dubin and are labeled as his. Party affiliations of early constitutional officers, which the official lists do not print, were drawn from secondary sources and checked against the party controlling the Legislature that elected them; unresolved cases are marked. Current officeholder data are verified against official sources each week. For the Supreme Judicial Court, dates are taken as printed where the Law Library and Cleaves Law Library lists agree; where they differ, the date consistent with the rest of the record (a reappointment seven years later, or a vacancy filled on the same day) is adopted and the discrepancy is noted. The party shown for each justice is that of the appointing governor, determined from the governor in office on the date of the commission.

Maps & Geography

The following records were used in the maps on the site and in assigning towns to the congressional, legislative and county commissioner districts in force for each election. The results, registration and demographics maps are drawn from the Census Bureau’s cartographic boundary files, which match the Bureau’s county-subdivision geography used for the demographic data; the official Maine GeoLibrary polygons are the source of the town boundaries in the project’s geography dataset and of the Legislature history maps.
