Quality of life – Regional index

The Quality of Life Index is a balance of all the themes that measure quality of life. Detailed indicators are normalised so that the values of all regions are placed on a scale from 0 to 100 where 0 is the worst and 100 is best (for some indicators, inverted scale is used). In the next step, the standardised indicator values are weighed together into indices at aspect level. This is done with averages, all indicators weighed together with the same weight in each aspect. The values are also at this level in the range 0 to 100. Then the index at aspect level is weighed together to the thematic level according to the same principle and these values also fall between 0 and 100. Finally, the value of all themes is weighed together according to the same principle, with the same weight, into an overall quality of life index.生活质量指数（Quality of Life Index）是衡量生活质量的全部主题维度的综合平衡结果。首先对细分指标进行标准化处理，使所有区域的指标分值均被映射至0至100的区间，其中0代表最差水平，100代表最优水平；部分指标采用反向计分规则。接下来，将标准化后的指标值加权聚合为维度层面指数，计算方式为求取平均值，即每个维度下的所有细分指标均赋予相同权重，该层面的分值同样处于0至100区间内。随后，依据相同原则将各维度层面的指数加权聚合为主题层面指数，此类分值同样处于0至100区间内。最终，基于相同原则、采用统一权重将所有主题层面的分值加权聚合，得到整体生活质量指数。
