<P> Some other developed countries are experiencing an increase in their birth rate, including France, which recorded a TFR of over 2.00 in 2008; the United Kingdom where TFR increased from 1.64 in 2000 to 1.98 in 2010; Australia, where the birth rate rose from 1.73 in 2001 to 1.93 in 2007 and New Zealand, where the TFR was 2.2 in 2008 . </P> <P> Israel is the only developed country that has never had sub-replacement fertility; a declining Arab and Bedouin fertility rate is countered by religious Jewish groups (mostly Haredim) with higher than average fertility rates . In addition, the (mostly non-religious) aliyah Jews from the former USSR shifted from a 1 child per woman fertility rate to an average fertility rate close to 2.2 children per woman . As of 2008, Israel's Jewish fertility rate is the highest among the industrial nations . </P>

 how long does it take a population with sub-replacement rates to actually decline
