The Jewish-Arab net income gap is a factor of 1.5 per household, but 1.9 per capita, i.e. Arabs have larger households. But Arab and Jewish birthrates are about even. Is it higher Arab poverty rates driving up multigenerational living rates?

@Alon
Just assuming here, but I'd guess that the larger households are due to (a) lingering effects of higher birth rates on the past and (b) multigenerational households, with grandparents, uncles etc
@NadavPV Haneen Shibli is pointing out on Bluesky that it's a combination of culture and overcrowding induced by state restrictions on homebuilding in the Arab sector.
