Of the above, 1,052,900 comprised couples with children, 719,600 comprised couples without children and 314,900 were single-parent nuclei (a father or mother with one or more children). Households with two or more nuclei (49,300 households) accounted for a very low percentage (1.6%), whereas households without a nucleus (867,600) accounted for 28.9% and the vast majority of these were single-person households (780,800).
