3. Data sources and 2015-relevant datasets

Conclusion

  • Temporal focus: metrics measured or reported in 2015; where unavailable, nearest-year proxies (2014–2016) used with notation.
  • Robustness: correlation analysis between subindices; principal component analysis to test dimensionality; bootstrapped confidence intervals for index estimates.
  • Limitations: cross-cultural meaning differences, survey nonresponse, platform data opaque or proprietary, inability to measure private emotional states directly.
