Inter-Regional Differences in Travel Time to the Nearest Nursery for Children with Mild Acute Illness in Japan

摘要

Access to day-care services for children with mild acute illness is important for working parents, because infants and toddlers often suddenly become ill, and most Japanese nursery schools do not accept children with even mild illnesses. Actual travel time to nurseries providing such day-care services is one of the indicators for measuring accessibility. However, this variable has not been well analyzed in previous work. To clarify practical access to such nurseries, this study used a car navigation algorithm to calculate the percentage of the population of children in Japan who can access nurseries providing services for children with mild acute illnesses within 15 to 30 minutes and compared this with the proportion of children living within a linear distance of 10 km of such nurseries. Of the 4,987,706 children younger than 5 years in 2015, 51.7% lived in areas from which the nearest nursery for children with mild acute illness was accessible within 0-15 minutes by automobile. In addition, 81.5% lived within 0-30 minutes of such nurseries, and the same percentage (81.5%) lived within a linear distance of 10 km of such nurseries. Both calculation methods (travel time and linear distance) showed inter-regional differences in accessibility, and the proportion of children with access to these nurseries was higher in heavily populated regions (e.g., Kanto and Kinki) than in less populated regions (e.g., Hokkaido and Tohoku). Children and caregivers throughout Japan should have equal access to these nurseries, because the national government subsidizes such services.
