An age\u2013period\u2013cohort (APC) analysis using the intrinsic estimator (IE) method was conducted to estimate the independent effects of age, period, and cohort.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The age-standardized TB mortality rate was 5.68 per 100,000, with higher rates observed in men, rural areas, and western regions. TB mortality among older adults declined overall from 2004 to 2021, although the rate of decline has slowed in recent years. The APC analysis revealed increased TB mortality with age, with the relative risk (RR) rising from 0.57 in the 60\u201364 age group to 1.53 in the 80\u201384 age group. The period effect decreased from 2007 to 2021, showing a higher risk effect in rural areas (RR\u202f=\u202f1.51) than in urban areas (RR\u202f=\u202f1.16) during 2007\u20132011, but this trend reversed in the period 2017\u20132021. The cohort effect generally declined, with the exception of certain demographic groups that showed an increase in the 1952\u20131956 and 1957\u20131961 birth cohorts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>TB mortality among older adults in China decreased from 2004 to 2021, although the decline has slowed in recent years.
