Many applications (such as health, urban planning, disaster response and environmental management) require information about the spatial distribution of aggregate populations i.e. they need to know where people are.
Ideally, such data would be specific to the time period of interest e.g. time of the day, weekday or weekend, school vacation or term-time or a particular season of the year.
But, in many cases, such space-time specific data are not available and investigators are forced to use a general dataset, such as the UK Census of Population.
The problem with the census and other routinely collected datasets is that they only capture the night-time, residential, location of the population.
This paper presents results from the ESRC-funded “Pop24/7” project which has developed both a conceptual framework and methodological approach for producing space-time specific gridded population models using census and a wide range of other publicly available data.
The paper outlines the innovative approaches of the Pop24/7 models, presents illustrative outputs from the project and discusses potential applications and limitations of the models.
