2.Israel: Even though there is no specific data on the percentage of Israelis with postsecondary education dating back to 1999, the numbers when compared to 2002 show that the growth is slowing considerably when compared to other countries. Around 46 percent of the adults aged from 25 to 64 had a tertiary education as of 2006. Just about 78 percent of the funds spent on educational institutions in Israel are of public funds. This is the only country where expenditure on educational institutions as a percentage of GDP decreased from 2000 to 2008. This country also had the highest increase in overall population with about 19.02 percent from 2000 to 2009.
