How to use this map
Sidebar controls
Research Area — dementia or alzheimer; both allow drill-down to cities and centres.
Period — drag the slider handles to choose any window of years (researcher counts may show ~ as approximations). Windows overlap, so never compare sums across them.
Continent — restricts the map, the listings and the ranking universe to one continent.
Indicator — the metric colouring the map, sorting the tables and driving the charts.
View — Indicators (map, year chart and listings) or Country collaboration (international collaboration network and heatmap).
📈 Ranking — appears for count indicators: year-by-year ranking evolution of the listed entities (Barcelona/Madrid/Spain always highlighted).
≥ N docs — hides entities below a documents threshold.
Groups / Leagues — alternative rankings: statistical technical ties (Poisson noise) or natural-break leagues; each group shares one position.
Export Excel — downloads the table as rendered.
Charts
Year chart — yearly evolution of the indicator; the selected period is highlighted.
Ranking chart — one line per listed entity; lower is better; historical collapses clip below the visible band (exact position in the tooltip).

Methodological notes
Countries shown — the 32 countries with 500 or more Dementia publications in 2021–2025. The remaining countries are grouped in the Other countries row and still count in the continent and world totals.
% Women — share of women among researchers whose gender could be identified; researchers of unknown gender are left out of the calculation. Earlier versions of this map divided by all researchers, so values are now higher (e.g. Spain rises above 50%). The unidentified share varies widely across countries, so this definition compares them more fairly.
