2014 baseline index data for assessment of African cities' inclusive urbanisation. This data set is the base data for the instrument described in the paper ‘A comparative measure of inclusive urbanisation in the cities of Africa’. The resultant index assesses, ranks and compares the potential for inclusive urbanisation of Africa’s leading cities in a scale that also allows for global comparison. The statistical processes underpinning the instrument were developed in the format described in the Appendix from 2013 onwards in studies that have varied in size, focus and source data. The parameters of the instrument have been defined to yield insights for investment, policy and theoretical development; be sufficiently flexible to include dominant cities across African states; allow comparison within and beyond Africa; incorporate indicators that reflect the span of inclusive urbanisation; and identify trends rather than the conditions that prevail at one time. The diagnostic instrument was developed to advance the theoretical specification of inclusive urbanisation in the African context, to identify promising policy interventions, and also to shed light on cities’ investment potential because demonstrable inclusive urbanisation attracts and rewards investment. The instrument and the data included in this spreadsheet are used as the baseline for comparison with three dimensions of ‘achieved inclusive urbanisation’ five years later, with the process and outcome of comparison described in the associated article.
