Persian-era Jerusalem was tiny: about 1,500 inhabitants, even as low as 500 according to some estimates.[16] It was the only true urban site in Yehud, the bulk of the province's population living in small unwalled villages. This picture did not much change throughout the entire Persian period, the entire population of the province remaining around 30,000. There is no sign in the archaeological record of massive inwards migration from Babylon.[17] The urban area did not include the western hill (containing the Jewish, Armenian and Christian Quarters of modern Jerusalem), which had been inside the walls before the Babylonian destruction.[18]
