Examining the social distributions in neighbourhood black carbon and ultrafine particles in Montreal and Toronto, Canada Open
Our findings highlight the importance of prioritizing exposure mitigation for populations residing near local sources and to understand contextual factors influencing inequities across cities and pollutants.

Measurement of urban vitality with time-lapsed street-view images and object-detection for scalable assessment of pedestrian-sidewalk dynamics Open
Principles of dense, mixed-use environments and pedestrianisation are influential in urban planning practice worldwide. A key outcome espoused by these principles is generating "urban vitality", the continuous use of street sidewalk infras…

Model-Based Prediction for Small Domains Using Covariates: A Comparison of Four Methods Open
We consider methods for model-based small area estimation when the number of areas with sampled data is a small fraction of the total areas for which estimates are required. Abundant auxiliary information is available from the survey for a…

From consumption to context: assessing poverty and inequality across diverse socio-ecological systems in Ghana Open
Local social and ecological contexts influence the experience of poverty and inequality in a number of ways that include shaping livelihood opportunities and determining the available infrastructure, services and environmental resources, a…

Mapping socio-economic status using mixed data: a hierarchical Bayesian approach Open
We propose a Bayesian hierarchical model to estimate a socio-economic status (SES) index based on mixed dichotomous and continuous variables. In particular, we extend Quinn’s ([2004]. Bayesian factor analysis for mixed ordinal and continuo…

Strangers in a strange land: Mapping household and neighbourhood associations with improved wellbeing outcomes in Accra, Ghana Open
Urban poverty is not limited to informal settlements, rather it extends throughout cities, with the poor and affluent often living in close proximity. Using a novel dataset derived from the full Ghanaian Census, we investigate how neighbou…

Geospatial modelling and socioeconomic inequalities of transportation, human, and nature-based sounds in Accra, Ghana Open
BACKGROUND AND AIM: Urban environments are filled with mixtures of mechanical, human, and nature-based sounds, which can be detrimental, neutral, or even beneficial to physical and psychological health. The majority of epidemiological stud…

Small Area Estimation with Random Forests and the LASSO Open
We consider random forests and LASSO methods for model-based small area estimation when the number of areas with sampled data is a small fraction of the total areas for which estimates are required. Abundant auxiliary information is availa…

Quantifying within-city inequalities in child mortality across neighbourhoods in Accra, Ghana: a Bayesian spatial analysis Open
Objective Countries in sub-Saharan Africa suffer the highest rates of child mortality worldwide. Urban areas tend to have lower mortality than rural areas, but these comparisons likely mask large within-city inequalities. We aimed to estim…

Changing Fortunes: An analysis of the dynamics of income inequality in US metropolitan areas Open
Income inequality has increased significantly in OECD countries over the last few decades. Rising inequality has been particularly pronounced in the United States, especially so in metropolitan areas. During this time, the increasingly une…

Identifying vulnerable urban neighbourhoods and their environmental, density, and housing characteristics in Accra, Ghana using census and remote sensing data Open
BACKGROUND AND AIM: Identifying vulnerable urban communities, commonly known as slums, can facilitate targeted policies to reduce urban economic and social inequities in cities, but these data are rarely available. We aimed to identify vul…

Spatial modelling and inequalities in community noise in Accra, Ghana Open
BACKGROUND AND AIM: Noise pollution is a growing environmental health concern in rapidly urbanising sub-Saharan African (SSA) cities. Yet mapping levels and variations of environmental noise in SSA cities has been scarce. METHODS: We measu…
