Data for: SAFE 2019: Updates and new sustainability findings worldwide

The SAFE model (Sustainability Assessment by Fuzzy Evaluation, http://www.sustainability.tuc.gr/) estimates the the overall sustainability of countries using relevant indicator data. The files (compressed, tab-delimited text) contain data on 69 sustainability indicators for 164 countries from 1990 to 2016. Three data sets are provided: 1) raw data as time series (810 out of a total of 69x164=11,316 time series are missing); 2) time series transformed into single values and normalized on a 0-1 scale from unsustainable to sustainable; 3) SAFE model inputs: a data set in which most of the missing values are imputed; for some countries certain indicators are intentionally omitted, estimated, or modified as explained in the article. Third-party sources of raw data are given in the article's supplementary Appendix E.SAFE模型（Sustainability Assessment by Fuzzy Evaluation，访问网址：http://www.sustainability.tuc.gr/），即基于模糊评估的可持续性评估模型，可依托相关指标数据对各国的整体可持续性水平进行评估。本次提供的压缩制表符分隔文本文件，涵盖了1990年至2016年间164个国家的69项可持续性指标数据。本次共提供三类数据集：1）原始时间序列数据（总计69×164=11316条时间序列，其中810条存在缺失）；2）经转换为单一数值并归一化至0-1区间的时间序列数据，该区间两端分别对应不可持续与可持续状态；3）SAFE模型输入数据集：该数据集对绝大多数缺失值进行了插补处理；部分国家的部分指标将按照论文中的说明被有意省略、估算或修正。原始数据的第三方来源详见论文补充附录E。
