On the Demographic "Threat"

This just out:

Data revealed a decline in the average of households’ size in the Palestinian Territory during the period between 1997 and 2011 from 6.4 persons in 1997 to 5.8 in 2011. This average declined in the West Bank from 6.1 persons in 1997 to 5.6 in 2011, while it declined in Gaza from 6.9 persons to 6.4 for the same period.

That was from today's report of the Palestinian Central Bureau of Statistics (PCBS).

What "threat"?
