Abstract
Simultaneous IJKs observations allow us to statistically select AGB stars, both M and C type, from RGB and younger or foreground stars in nearby galaxies. Regions of different metallicity identified from the distribution of the C/M ratio show a considerable variation across the surface of the Magellanic Clouds and NGC 6822.
