The Invest in Childcare initiative is conducting a cross-country global study on childcare in 10+ countries to understand to what extent childcare is currently available; affordable; of good quality and meeting the needs of families; and where the opportunities may be to expand access and improve systems. The objectives are to:** Generate comparable data on childcare across countries to increase the understanding of the childcare sector globally and potential for growth.** Inform dialogue; policy reforms and investments in childcare; globally and in specific countries.** Increase the number of countries with return on investment (ROI) estimates for increasing women’s employment through childcare services. The study will be carried out through a mixed-methods approach; in nationally representative samples (or at the State/Province level for countries that are doing sub-national studies); comprising of four core components: (i) demand-side assessment; (ii) supply-side assessment; (iii) enabling environment review; and (iv); in a sub-set of countries; assessment of potential for private sector finance. The Terms of reference is attached with details of the tasks and deliverables.[1] For more information on the sampling strategy for the supply-side survey please refer to the section Key information on study design; sub-section on sampling.
