“…The 2SFCA method quantifies the potential spatial accessibility of services, or the theoretical and aggregate availability of services conditional on assumptions regarding travel route, time, speed, and/or distance (McGrail 2012). Past research has used the 2SFCA method to analyze the potential spatial accessibility of small areas to a variety of health and social services, including primary care, medical clinics, daycare centres, parks, and emergency shelters (Luo and Qi 2009; McGrail and Humphreys 2009; Ngui and Apparicio 2011; Hu et al 2020; Su et al 2022).…”

Cooling centres provide respite, safety, and social support during extreme heat events for populations that do not have the resources to own or operate in‐home air conditioning. The objective of this study was to measure the spatial accessibility of cooling centres and analyze the associations between cooling centre access and marginalization in Montreal, Toronto, and Vancouver, Canada. The potential spatial accessibility of cooling centres within a 15‐minute walk was measured at the dissemination area scale using the two‐step floating catchment area method. A two‐stage modelling approach was used to analyze the associations between cooling centre access and marginalization. Approximately 62%, 58%, and 54% of the populations in Montreal, Toronto, and Vancouver had access to at least one cooling centre. In Montreal and Vancouver, high marginalization areas were more likely to have cooling centre access than low marginalization areas. Of the areas with cooling centre access, smaller access scores were observed in areas with high residential instability. Approximately one‐fifth of the areas in each city had no cooling centre access and high marginalization, and may be considered for future cooling centres or programs that improve accessibility to existing centres.

“…Two-Step Floating Catchment Area Method (2SFCA) was first proposed by Radke et al [ 15 ]. 2SFCA considers both supply and demand, and analyzes the supply and demand in the study area, so it is widely used in the accessibility evaluation of public service facilities [ 16 – 19 ]. The traditional 2SFCA thinks that the accessibility value of facilities within the search threshold range is the same, but in reality, the residents’ travel intention will decrease with the increase of travel distance.…”

As the aging of China’s population continues to deepen, a number of elderly care facilities relying on community platforms to provide home care services have been established in urban communities, effectively alleviating the problem of difficult community elderly care, while a spatial mismatch between the facilities and the elderly population has also emerged. To solve this problem, this paper analyzes the equity in walking access to community home care facilities for elderly people with different mobility abilities in Lianhu District of Xi’an City, taking the resources of community home care facilities as the research object. Firstly, the coverage rate of the facilities was calculated based on the 15-minute walking range of the elderly with different mobility, and the accessibility of the facilities was measured using the Kernel Density-type two-step moving search method. Then, Gini coefficient, Lorenz curve and location entropy were used to analyze the spatial matching pattern of facilities and elderly population. The results show that there is a serious spatial mismatch between the resources of community home care facilities and the elderly population with mobility restriction. In addition, the available facility area per capita is low for more than 80% of the elderly with mobility restriction, and the road network density has a significant impact on the access of the elderly with mobility restriction to the community home care facility resources. These research results indicate that the spatial layout and configuration of community home care facilities are unfair to the elderly with poor mobility, and that these elderly care facility configurations do not favor the disadvantaged groups.

“…[33] focuses on measuring accessibility. An interpretation of these results through Economic-Geographical metrics is offered in relatively recent articles [10][11][12] which utilize the Gini coefficient. However, none of the other Economic-Geographical metrics was used.…”

“…We combine established metrics with standard statistics, such as arithmetic mean or maximum distance, to obtain a more robust analysis. As far as we know, the discussion in literature is usually limited solely to the Gini coefficient, see [10][11][12], and the introduction of other Economical-Geographical metrics has not been conducted in this field yet. Moreover, we think the discussion about the Gini coefficient lacks acknowledging its drawbacks.…”

In this article, we aim to develop the theoretical background for the possible application of Economic-Geographical metrics in the field of population protection. We deal with various options for analyzing the availability of “safety” for citizens using studied metrics. Among others, we apply well-known metrics such as the Gini coefficient, Hoover index and even establish their generalizations. We develop a theoretical background and evaluate our findings on generated and actual data. We find that the metrics used can have an opposite interpretation depending on the scenario we are considering. We also discover that some scenarios demand a modification to the usual metric. We conclude that Economic-Geographical metrics give valuable tools to address specific security challenges. Metric’s generalizations could serve as a potent tool for other authors working in the field of population protection. Nevertheless, we must keep in mind that metrics also have drawbacks.
