The effect of population size on the estimated maximum false match rate.

Estimation assumes:

• 22 years of birth dates, uniform distribution (compromise distribution).

• single-date (exact end-date) matching only of separations to residential aged care admissions.

• exact period matching to residential aged care hospital leave.

Calculations use national average hospital separation rates (2000–01) and residential aged care admission and residential aged care leave rates (2001–02) [38]. Estimates take into account the distribution of hospital episodes by length of stay.
