  1. Indirect estimates of Hidden populations : capture-recapture methods to estimate the numbers of heroin users in the Australian Capital Territory.

    Article - En anglais

    This paper describes a method of estimating the size of a population based on matching the individuals from the population appearing in two or more nonrandom samples.

    The method has been developed by population biologists and demographers who have shown that the simple estimates based on only two samples are very sensitive to the assumption that the two samples are independent.

    This assumption is rarely met with human populations.

    However, estimates based on three or more samples can be derived by fitting a loglinear model to a 2'contingency table.

    The method is applied to a data set of heroin users seeking treatment or counselling or arrested on drug charges in 1988 or 1989 in a small Australian city.

    The method produced a stable estimate of 1250 heroin users.
