Rome at Its Height: Perhaps a Million People, Most of Them Immigrants or Their Descendants
Historian Ryan R. Abrecht calls ancient Rome a city of immigrants: a pre-modern metropolis of perhaps a million people at its height, most of them immigrants or the descendants of immigrants.
Modern historians overwhelmingly agree that immigration profoundly shaped Rome's demographics and history. What they have argued over is community: some have held that there was little sense of immigrant community at Rome at all.
At the scale of a single district the picture sharpens. By the first century CE, the Roman district beyond the Tiber had become what we would now call an immigrant neighborhood — a veritable Little Middle East. That is a claim about streets, not about the whole city, which is what makes it useful against a verdict delivered at citywide scale.

The fault line here isn't numbers at all. A city can be overwhelmingly composed of newcomers and their children and still have thin institutions binding them to one another.
An immigrant neighborhood is exactly where the weak-ties verdict should strain: clustering in one district is hard to square with foreigners whose connections were mostly ephemeral.
Careful, though — what we would now call an immigrant neighborhood is a modern label fitted onto an ancient district. It tells us about clustering; it doesn't tell us how the residents thought about themselves.
