More and more migrants

After finishing the next chapter of the dissertation, in which I combined the strontium and oxygen isotope data, I have even more immigrants than before - well over 1/3 of the sample was outside the bounds of one or both isotopes. I got to whip up some pretty awesomesauce charts, like this one (the labelled people are immigrants):

Finding homelands is difficult, particularly since the bioavailability of strontium in the region is unknown owing to no previous human enamel studies. But I seem to have people from various parts of the Italian peninsula and some from warmer, drier areas: Greece, Asia Minor, north Africa perhaps. There were more male immigrants than female immigrants, and a surprising number of kids came to Rome before the age of 15.

Next up is the best part - characterizing immigrants' lives through pathology, dietary, and archaeological information to see, particularly, if they had a different experience in Rome than their local brethren. Then, a couple chapters introducing/concluding the study, and the dissertation is complete. Easier said than done, of course. But it's time to choose work over sleep, at least for the next couple of months.
