Some introductory highlights from the data are discussed below with links for further information.
This website has received 500,000 visitors since 2020, illustrating the widespread interest in global population geography. The GHSL records the complexity and diversity of human settlement, beyond simple rural-urban divisions. Integrating huge volumes of satellite data with national census data, the GHSL describes in detail the settlement geography of the entire globe, and has applications for a wide range of research and policy related to urban growth, development and sustainability. The data is from the Global Human Settlement Layer (GHSL) 2023 produced by the European Commission JRC and the Center for International Earth Science Information Network at Columbia University. This interactive map shows population density in 2020, measured in residents per square kilometre. As with all scientific research, there is also a risk of publication bias.Visualising Population Density Across the Globe These results are promising, but more research is needed to determine the connection between improved assessment scores and everyday tasks in participants' lives.įuture research should address the risk of inadvertent experimenter bias and the risk of attrition bias in this study, as both the Lumosity and crossword groups had approximately 50% attrition rate. In it, half of the 4,715 participants who completed the study trained five days per week, for fifteen minutes each day on Lumosity while the other half did online crossword puzzles as an active control.Īfter 10 weeks, Lumosity users improved more than the control group on our assessments of working memory, short term memory, processing speed, problem solving, fluid reasoning, and overall cognitive function. Lumos Labs conducted a randomized study of Lumosity brain training and published the results in a peer-reviewed research journal.
