Projected Deaths per 100,000 Due to Temperature Change (2040-2059 Annual Average)
The mean projected change in annual death rates per 100,000 people in a country that resulted from the impact of climate change on daily temperature, in contrast to a future scenario where climate change is absent.

Urban Population Living in Slum Households (%)
The percentage of the urban population living in slum households. A slum household is defined as a group of individuals living under the same roof lacking one or more of the following conditions: access to improved water, access to improved sanitation, sufficient living area, housing durability, and security of tenure. While the term slum has a derogatory connotation, it continues to be used in data collection categories such as this one. Data are for the most recent year available since 2018 and are from UN-HABITAT.
-
Moderate/Severe Food Insecurity (%)
The percentage of the total population estimated to be experiencing difficulties in obtaining sufficient, safe, and nutritious food for healthy living. Moderate food insecurity implies compromised food quality and quantity, accompanied by concerns about food access due to financial constraints. Severe food insecurity extends to individuals who have entirely depleted their food supply, even going without meals for days. Data presented are the three-year average between 2020 and 2022 and are from the FAO.
