Number of resources/school-age population * 100%. Allocation rate of preschool education resources = number of preschool education resources/number of school-age children * 100%. The allocation rate of preschool education resources is an index to measure the coverage rate of preschool education services. Higher allocation rate means that preschool education resources are relatively sufficient to meet the needs of more school-age children. On the contrary, the low allocation rate means that preschool education resources are not enough to meet the needs of all school-age children, so it is necessary to further increase investment and resource allocation.
