Baseline Resilience Indicators for Communities (BRIC) Index

The Baseline Resilience Indicators for Communities Index aims to help identify communities that are resilient to natural hazards. This BRIC data set contains polygon layers for the overall Hazards Vulnerability and Resilience Institute (HVRI) BRIC using six capitals (Social, Economic, Community, Economic, Institutional, Housing and Infrastructural, and Environmental) based on county-level inputs from 2010, 2015, and 2020. The files contain all six capital scores and the BRIC score for each county. BRIC values range from 0 to 6 based on the six capital scores ranging from 0 to 1. Capital scores are calculated from min-maxed values of each of their component variables. For all variables, capitals, and the BRIC values, 0 represents the lowest community resilience, and higher values represent the most resilient counties. The data are provided for the entire United States following the county geography of the year the BRIC was created and for the contiguous United States following the county geography of the year the BRIC was created. 2010 BRIC is only available for the contiguous United States.社区基线韧性指标（Baseline Resilience Indicators for Communities Index，简称BRIC）旨在助力识别具备自然灾害韧性的社区。本BRIC数据集包含灾害韧性与韧性研究所（Hazards Vulnerability and Resilience Institute, HVRI）开发的整体BRIC多边形图层，该图层基于2010、2015及2020年的县级输入数据，涵盖六大资本维度：社会资本、经济资本、社区资本、经济资本、制度资本、住房与基础设施资本以及环境资本。数据集包含所有六大资本得分与各县级单元的BRIC得分。BRIC的取值区间为0至6，其计算依托取值范围为0至1的六大资本得分；资本得分由各组成变量的最小-最大归一化值计算得到。对于所有变量、资本维度及BRIC值，0代表社区韧性水平最低，数值越高则对应县域的韧性越强。本次发布的数据覆盖全美及美国本土连续区域，均采用对应BRIC版本编制年份的县级地理边界；其中2010年版BRIC仅对美国本土连续区域开放。
