Stellar Population

(grouping of stars according to metallicity)

A Stellar Population is a grouping of Milky Way stars based upon their Metallicity:

These show a qualitative Age-Metallicity Relation (AMR). A quantitative relation has been theorized, i.e., that ages could be derived from observed metallicity, but I believe this is not currently considered reliable.
