Mansfield Park

Egerton's London 1814 three-decker is the true first and the census claim is confirmed; Austen published on commission and retained the copyright. John Murray's 1816 second edition (Gilson A7, three volumes, about 750 copies) carries Austen's own revisions and is collected in its own right, but it is not the first — its title reads "By the Author of Pride and Prejudice", and copies commonly lack half-titles. It sold poorly (only 252 copies by January 1820, then remaindered). The first American edition is Philadelphia: Carey & Lea, 1832, two volumes in drab boards with cloth spines and paper labels — notable because it precedes any British reprint of the novel, but it is a reprint, not the first.
