Dementia ascertainment was operationalized using the Langa\u2013Weir (LW), Expert, Hurd, and LASSO classifications. We test for both within-group differences (i.e., nativity for Latinos) and gender differences to comprehensively document the overall burden of dementia among at-risk populations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Expert, LASSO, and Hurd competing algorithm estimates were generally equal to the LW estimates for dementia prevalence after age 70, with a few exceptions.
