The average size, number and distribution by size of private households in Turkey are projected based on
the official population projection and an extension of the headship rates method. Our results imply the
plausibility of a quadrupled number of single-person households along with almost a doubling of the
overall number of households in 2000-2025. Appreciating these changes is essential for evaluating
housing needs, socio-economic developments and environmental issues in Turkey. Under current
consumption patterns, change in households’ composition is potentially more important for economic
growth prospects than the population growth.
