Perspective 4—based on the concept of eco-sustainable human development index (E-SHDI) (Ture 2013). The details of this perspective are given in Eq. (6) described in the “Materials and Methods” section of this paper

Note the details of the raw data are given in Fig. S1

^aPotential external environmental impact

^bThe annual population growth rate (APGR) was considered to be inversely related with sustainability because Baguio City has already greatly surpassed its designed population ceiling of 25 000 people (Glorioso 2006; Cariño 2009; Estoque and Murayama 2013a). Baguio City already has a population density of 5543 people km⁻², and thus an increase in its APGR would exacerbate congestion
