Match Accuracy calculated based on Same-sex Matches by Number of Individuals living at same coordinate. (Note: In this figure we calculate the likely probability that a matched couple is indeed married to each other. For this we assume that the number of matched male/male and female/female couples obtained by using the same algorithm as for matched male/female couples is a proxy for the number of false matched. The accuracy can then be calculated as: [N(f/m) − N(f/f) − N(m/m)]/N(f/m). The figure plots this accuracy rate as a function of the number of individuals who live at the same coordinate where the couple is matched)
