Light poverty is the state or condition in which people or communities lack artificial or electric light after sunset. This originates from many social and economic reasons, including inability to afford efficient lighting.[1] Light poverty may also occur when a country's national grid has not electrified rural areas requiring light.[2] As of 2019, 1.1 billion people do not have access to light, and this has many social and economic consequences, such as children being unable to study and rural markets and businesses being unable to operate due to the lack of visibility.[1][3]
