{"chart":{"slug":"nih-funding-by-disease","title":"How much does NIH spend researching major diseases?","takeaway":"Cancer research got the most NIH money of these major diseases in fiscal 2025, $6.97 billion, followed by HIV/AIDS ($3.95 billion) and Alzheimer's and related dementias ($2.99 billion); opioid research got $825 million. The categories are NIH's own (RCDC), and a project that studies two diseases counts in both. These are totals of the projects listed in RePORTER, so they differ somewhat from NIH's published category estimates.","topic":"Medical research","chart_type":"bar","ranking":false,"x_label":"Disease (NIH spending category)","y_label":"NIH funding (dollars)","unit":"dollars","points_count":15,"source":{"name":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC)","url":"https://report.nih.gov/funding/categorical-spending"},"license":{"name":"Public domain (U.S. government work)","url":"https://www.usa.gov/government-copyright"},"data_as_of":"2025-09-30","updated_at":"2026-10-17T18:50:41.475Z","url":"https://chart.ly/charts/nih-funding-by-disease","api_url":"https://chart.ly/api/v1/charts/nih-funding-by-disease","csv_url":"https://chart.ly/charts/nih-funding-by-disease/data.csv","image_url":"https://chart.ly/charts/nih-funding-by-disease/image.png","embed_url":"https://chart.ly/charts/nih-funding-by-disease/embed","credit":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC), via Chartly (https://chart.ly/charts/nih-funding-by-disease)","credit_html":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC), via \u003ca href=\"https://chart.ly/charts/nih-funding-by-disease\"\u003eChartly\u003c/a\u003e","average_label":null,"zero_axis":true,"data":[{"label":"Cancer","value":6971923613},{"label":"HIV/AIDS","value":3952073353},{"label":"Alzheimer's and related dementias","value":2991568139},{"label":"Heart disease","value":1695040418},{"label":"Obesity","value":1086443218},{"label":"Diabetes","value":1011114540},{"label":"Opioids","value":824934646},{"label":"Breast cancer","value":691680360},{"label":"Depression","value":665483530},{"label":"Tuberculosis","value":561007295},{"label":"Stroke","value":413805063},{"label":"Lung cancer","value":384789881},{"label":"Autism","value":323222681},{"label":"Parkinson's disease","value":234449748},{"label":"Malaria","value":208907222}],"annotations":[]},"docs":"https://chart.ly/developers","terms":"Free to use with credit: wherever you show or quote a chart's data, name Chartly with a link to that chart's url (each chart's credit line does both) and credit its source as its license asks.","credit":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC), via Chartly (https://chart.ly/charts/nih-funding-by-disease)"}
