Title
Haiti And Domrep - Accessibility Indicators
Description
This dataset provides insights into spatial accessibility to healthcare and education services across Haiti And Domrep. It has been created using free and open tools such as [openrouteservice](https://openrouteservice.org/) and open data sources, primarily [OpenStreetMap](https://www.openstreetmap.org/) (OSM). To assess accessibility to education and healthcare, we use travel-time isochrones—polygons representing areas reachable within a given time or distance by car. We overlay these isochrones with [WorldPop](https://www.worldpop.org/) population data, which provides 100m-resolution estimates. This allows us to calculate the population within time intervals from 10 to 120 minutes away from hospital services and distance intervals from 5 to 50 km away from schools. The unit of analysis is defined by [geoboundaries](https://www.geoboundaries.org/) country borders, and where available we also summarise results at finer administrative levels (ADM 1-4). Data Structure: - **name**: Region or country name. - **iso**: ISO3 country code. - **id**: Unique identifier for the administrative unit. - **country**: ISO3 country code. - **admin_level**: Administrative level of the unit. - **category**: Service category — `education`, `hospitals` or `primary_healthcare`. - **range_type**: Method used for the catchment zone — `distance` or `time`. - **range**: Distance (in meters) or Time away (in seconds) from schools used to generate the polygon. - **population**: Total population within the specified range. - **school_age_population**: Number of school-age individuals within the range. - **school_age_population_share**: Cumulative percentage of school-age population. - **school_age_population_interval**: Incremental school-age population added in the current distance band. - **school_age_population_interval_share**: Proportion of new school-age population in the current interval. - **population_share**: Cumulative percentage of total population. - **population_interval**: Incremental population added in the current distance band. - **population_interval_share**: Share of the total population represented by the current interval. This dataset is one of many [HeiGIT exports on HDX](https://data.humdata.org/organization/heidelberg-institute-for-geoinformation-technology).
