In 2005, the total population grew by 13,000 (1.8%)—similar to the Israeli national average, but the religious and ethnic composition is shifting. While 31% of the Jewish population is made up of children below the age fifteen, the figure for the Arab population is 42%. This would seem to corroborate the observation that the percentage of Jews in Jerusalem has declined over the past four decades. In 1967, Jews accounted for 74 percent of the population, while the figure for 2006 is down nine percent. Possible factors are the high cost of housing, fewer job opportunities and the increasingly religious character of the city, although proportionally, young Haredim are leaving in higher numbers. The percentage of secular Jews, or those who 'wear their faith lightly' is dropping, with some 20,000 leaving the city over the past seven years (2012). They now number 31% of the population, the same percentage as the rising Haredi population. Many move to the suburbs and coastal cities in search of cheaper housing and a more secular lifestyle.
