The average household size in Morocco is falling, although households in urban areas tend to be smaller (4.8 in 2012; average 4.6 in 2000-2006) than in rural areas (5.6 in 2012; average 6.4 in 2000-2006; data Ministry of Economy and Finance).
Between the late 1970s and the early 1990s, the total fertility rate (TFR) in Morocco declined by 44 percent, a rapid decrease compared, for example, with Egypt. One reason was that the median length of time between births increased, as the wish among Moroccan women for large families decreased: the size of the ideal family in a survey of Moroccan women declined from 5 children to 3.7. This became a realizable desire because of the growing availability of contraception, which increased from 19.4 percent of women aged 15-49 in 1980 to 41.5 percent in 1992 to 63 percent in 2004 (World Bank World Development Indicators). Another factor was the increase in the mean age of marriage between 1971 and 2004, from 19.1 years to 26.4 years for women and from 25 years to 31.2 years for men (UN World Marriage Data 2008). This change was influenced by gains in female education and by the economic difficulties of saving enough money to marry.
Many Moroccan households are headed by women, the result of high levels of male migration. In 2004, the World Bank reported that 17 percent of households were headed by women. This is a situation of long standing: in the mid-1990s, 16 percent of households were headed by women, and 10 percent of the population lived in such households. This was a strong indicator of poverty: women head of households tended to be less well educated: 20 percent had no education, only 6 percent had secondary or higher education, and 90 percent of them were the only adult in a family of children. 23 percent lived in households with no running drinking water, no toilet facilities, and no electricity. This may change, as more women are migrating.
