The identification of 53 faint planetary nebulae (PN) in the Magellanic Clouds has allowed the determination of the planetary nebula luminosity function, which provides a guideline for extrapolation of insufficiently deep surveys of more distant galaxies to estimate the total number of PN in those galaxies. A review of the luminosity specific number of PN in 10 local group galaxies suggests that this parameter provides adequate consistency for estimating the total number of PN in our Galaxy, which is found to be 10,000 plus or minus 4000.
