Key villages have focused services, with good transport links to nearby villages, so that they can provide services to the whole area, which reduces rural depopulation.
Rural depopulation was causing the loss of services as people moved to the city, but counter urbanisation is bringing services back as the villages increase in size.
Remote rural areas are losing services due to rural depopulation.
In LICs and MICs, the nature of services changes as people move rom rural to urban areas:
less tax revenue due to a smaller workforce, so basic services are reduced e.g. primary school, transport, health clinics
smaller populations contribute fewer votes, so the areas are less important to politicians
