Spatial inequalities of life expectancy in Hong Kong, 2010–2024
Hong Kong ranks among the world’s longest-lived populations, yet it remains unclear how uniform this achievement is across the territory. We conducted an ecological study of all 18 Hong Kong districts from 2010 to 2024. Age- and sex-specific mortality rates were modelled using Bayesian adaptation of the Tool for Projecting Age-Specific Rates using Linear Splines (TOPALS), from which annual period life tables were constructed to estimate life expe…
Geospatial analysis of Covid-19 vaccine access in Kenya
Background: COVID-19 vaccines have reduced severe illness and mortality, yet inequitable distribution delayed rollout in many low- and middle-income countries (LMICs), including Kenya, where only 36% of adults were fully vaccinated by October 2022. While sociodemographic and attitudinal determinants of uptake are well documented, role of geographic access remain underexplored at individual level. This study assessed population coverage by travel …
Real-time physiological and emotional responses to the deadly Tai Po fire in Hong Kong
Evaluating geographic accessibility to Covid-19 vaccination across 54 countries/regions
BACKGROUND: The COVID-19 pandemic has revealed significant disparities in global vaccine accessibility, particularly affecting low and middle-income countries (LMICs). However, current research on COVID-19 vaccine accessibility primarily focuses on individual countries or high-income countries (HIC). We aimed to evaluate geographic accessibility to COVID-19 vaccination on a multicountry scale, covering comparisons across LMICs and HICs. Additiona…
Spatial Disparities in Access to Public and Private Long-Term Care Facilities in Hong Kong
Long-term care facilities (LTCFs) provide institutional care for older adults, which improves their overall quality of life. Hong Kong, with a 20.5 percent aging rate in 2021, is now one of the world’s most rapidly aging cities. Few studies have systematically examined disparities in spatial accessibility between public and private LTCFs, particularly in high-density aging societies. This study addresses this research gap by evaluating spatial ac…
Innovations in mapping health & structural drivers of disease & well-being
1. In this special issue on Mapping Health, we highlight how researchers have visualized health events, interactions, and services, as well as the complex, multidimensional factors driving health d
Measuring access to culturally appropriate food and associations with diabetes among Asian Americans and Native Hawaiians or Pacific Islanders
Objective: The Food Access Research Atlas (FARA) is a common measure of food access developed by the US Department of Agriculture. However, its sole focus on supermarkets lacks specificity for culturally appropriate food. This ecological study assesses the relationship of FARA and our novel Yelp-based Ethnic Store Measure with diabetes rates among Asian Americans and Native Hawaiians or Pacific Islanders (AAPI). Design: This study leveraged crowd…
Designing and Evaluating a Hierarchical Framework for Matching Food Outlets across Multi-sourced Geospatial Datasets
Connectivity analysis in pedestrian networks
Understanding the spatial heterogeneity of Covid-19 vaccination uptake in England
Our findings indicate the importance of improving the spatial accessibility to vaccinations in developing regions and among specific population groups in order to promote COVID-19 vaccination
Accessibility Assessment of Buildings Based on Multi-Source Spatial Data
The question of whether each building of housing estate has equal access to nearby social service resources (e.g., public transportation service, catering, entertainment, etc.) is a major concern of citizens. This paper takes Wuhan as a case to explore the equality in social service resource sharing of the housing estate at a microscopic level by analyzing the accessibility of each building under different travel patterns. To estimate the accessi…
