**Appendix A**

The tables reported below (Tables A1–A4) summarize the geographic scope and UGI research focus of the case study, empirical, and documentary research reported in the 87 articles analyzed by Parker and Simpson [14], the 171 articles analyzed by Parker and Zingoni de Baro [16], and the 38 UGI related articles cited as evidence in support of the synthesis of the URT and HNCT presented in this article.


**Table A1.** Geographic distribution of case studies and sources of data that informed this article.

1. Data extracted from included articles published in Data Descriptor by Simpson and Parker [17]. 2. Data extracted from included articles published in Data Descriptor by Parker and Simpson [19]. 3. The global-scale analysis of GIS data by Richards and Belcher [43] that covered the five most inhabited continents was coded as a Global Review article.


**Table A2.** Number of countries represented in the case studies and sources of data that informed this article.

1. Data extracted from included articles published in Data Descriptor by Simpson and Parker [17]. 2. Data extracted from included articles published in Data Descriptor by Parker and Simpson [19]. 3. Richards and Belcher [43] conducted a global analysis of GIS data that covered multiple countries on each of the five most inhabited continents.

**Table A3.** Number of cities reported in the case studies and sources of data that informed this article.

In addition, Richards and Belcher [43] conducted a global review of GIS data that graphically reported UGI data for at least 1000 cities across all five of the most inhabited continents (excluding Antarctica). 4. In addition, Biega ´nska et al. [37] report a GIS-based country-scale comparative analysis of the UGI provided in peri-urban developments associated with approximately 100urbancentersinGermany,Latvia,andPoland.

**Table A4.** Focus for case studies of the aspects of urban communities and development that informed thisarticle.
