Demographic Pressures, Social Indicator (Fragile state Index) 2018

The Demographic Pressures Indicator considers pressures upon the state deriving from the population itself or the environment around it. For example, the Indicator measures population pressures related to food supply, access to safe water, and other life-sustaining resources, or health, such as prevalence of disease and epidemics. The Indicator considers demographic characteristics, such as pressures from high population growth rates or skewed population distributions, such as a “youth or age bulge,” or sharply divergent rates of population growth among competing communal groups, recognizing that such effects can have profound social, economic, and political effects. Beyond the population, the Indicator also takes into account pressures stemming from natural disasters (hurricanes, earthquakes, floods or drought), and pressures upon the population from environmental hazards.

Quality/Lineage: The data is downloaded from the above link http://fundforpeace.org/fsi/indicators/s1/ and manipulated only table format keeping the value same for all the countries as the requirement of the Strive database. The map is created based on the values of the country using rworldmap package in R.

人口压力指标（Demographic Pressures Indicator）用于考量由人口自身或其周边环境给国家带来的各类压力。例如，该指标可衡量与粮食供应、安全饮用水获取及其他维持生命的资源相关的人口压力，或是与健康相关的压力，如疾病与流行病的流行情况。该指标纳入人口特征相关的压力因素，例如高人口增长率带来的压力、人口分布失衡的情况——比如“青年膨胀 (youth bulge)”或年龄结构失衡，或是相互竞争的社群群体间人口增长率差异悬殊的情形，并充分意识到此类影响可能对社会、经济与政治产生深远效应。除人口因素外，该指标还纳入了由自然灾害（飓风、地震、洪水或干旱）引发的压力，以及环境风险给人口带来的压力。

数据质量与溯源：本数据集从上述链接http://fundforpeace.org/fsi/indicators/s1/ 下载获取，仅对其进行表格格式调整，且严格遵循Strive数据库的要求，保留了所有国家的原始数值不变。本次可视化地图基于各国的指标数值，利用R语言的rworldmap包制作完成。
