Two-party-preferred tables

(Edit 2015-11-27: I have made a slight change to the TPP estimate method, which alters slightly some of the numbers below. The original numbers, posted on 2015-09-03, are here. Edit 2015-11-28: I had earlier omitted the results for 1974 in the second table; these are now shown.)

The following table contains my estimates for the Labor share of the two-party-preferred vote in elections from 1919 to 1980, and the exact figures from 1983 to 2013 (including a guess for Newcastle in 1998). Several of the Northern Territory figures are entirely guessed. I describe my methodology on the data page.

The following table allows comparisons of estimates for the Labor share of the two-party-preferred vote by me (DB), Adam Carr (AC), Colin Hughes (CH), the late Joan Rydon, and Malcolm Mackerras (the latter two combined in a single series, R/M). Carr's estimates are from here, Hughes's estimates are those on the AEC website, and the Rydon/Mackerras series is gleaned from several sources. Mumble posted scans of tables provided by Mackerras for 1937-1958. These contain Rydon's estimates for 1937-1943 and 1951-1955, and Mackerras's estimates for 1946, 1949, and 1958. Mackerras's estimates for 1961-1974 are in his book Elections 1975, pp192-3. His estimates for 1975 and 1977 are from his monograph Australian General Election and Senate Election, December 10, 1977: Statistical Analysis, and for 1980 from Australian General Election and Senate Election 1980: Statistical Analysis.
