Public services are essential to satisfy the needs of healthcare, education, justice, etc. in citizens’ daily life. Thus, individuals need these services in a certain proximity to their homes. Nonetheless, in big cities, some public services are not close enough. To tackle this problem, we propose a methodology to compute a Government Public Services Presence Index for measuring how well different zones are in a city are served. We apply our methodology to the city of Lima, showing the utility of the index while being simple to understand. We profile fifty different districts in four groups, allowing policymakers and urban planners to observe the lack of public services.
