According to the 1995 U.S. Census Bureau Survey of Income and Program Participation (SIPP), over thirty-six percent of families of preschoolers with working mothers primarily relied on childcare in the home of a relative, family daycare provider or other non-relative. Almost twenty-six percent of families used organized childcare facilities as their primary arrangement.[90]

Spain provides paid maternity leave of 16 weeks with 30-50% of mothers returning to work (most full-time) after this[citation needed], thus babies 4 months of age tend to be placed in daycare centers. Adult-infant ratios are about 1:7-8 first year and 1:16-18 second year.[citation needed] Public preschool education is provided for most children aged 3–5 years in "Infantil" schools which also provide primary school education.[citation needed]
