This happens in sizable cities with many health and farm improvements that then get exterminated. The reason being that the squalor from the large population is no longer present, yet the buildings that provide the health bonuses are still there. Once you get a sufficiently large growth rate (I think 6 or 7%) you get a pretty hefty bonus to happiness. After all, whether you're Roman or Hun, Egyptian or Celtic, everyone likes a little horizontal boogie.
