Population Health Measures: Age-Adjusted Mortality Rates

Age-adjustment mortality rates are rates of deaths that are computed using a statistical method to create a metric based on the true death rate so that it can be compared over time for a single population (i.e. comparing 2006-2008 to 2010-2012), as well as enable comparisons across different populations with possibly different age distributions in their populations (i.e. comparing Hispanic residents to Asian residents).
Age adjustment methods applied to Montgomery County rates are consistent with US Centers for Disease Control and Prevention (CDC), National Center for Health Statistics (NCHS) as well as Maryland Department of Health and Mental Hygiene’s Vital Statistics Administration (DHMH VSA).
PHS Planning and Epidemiology receives an annual data file of Montgomery County resident deaths registered with Maryland Department of Health and Mental Hygiene’s Vital Statistics Administration (DHMH VSA).
Using SAS analytic software, MCDHHS standardizes, aggregates, and calculates age-adjusted rates for each of the leading causes of death category consistent with state and national methods and by subgroups based on age, gender, race, and ethnicity combinations. Data are released in compliance with Data Use Agreements between DHMH VSA and MCDHHS. This dataset will be updated Annually.

年龄调整死亡率系采用统计学方法计算，以构建基于真实死亡率的指标，从而能够对单一人群在不同时间点（例如，比较2006-2008年与2010-2012年）进行对比，并允许可能有不同年龄分布的不同人群之间进行比较（例如，比较西班牙裔居民与亚裔居民）。蒙哥马利县的年龄调整方法与美国疾病控制与预防中心（CDC）、国家健康统计中心（NCHS）以及马里兰州卫生与心理健康部生命统计管理局（DHMH VSA）的方法保持一致。公共卫生规划与流行病学部门每年从马里兰州卫生与心理健康部生命统计管理局（DHMH VSA）接收蒙哥马利县居民死亡登记的年度数据文件。利用SAS分析软件，MCDHHS对与州及国家方法一致的各类主要死亡原因进行标准化、汇总和年龄调整率的计算，并按照年龄、性别、种族和族裔组合的子群体进行划分。数据发布遵守DHMH VSA与MCDHHS之间的数据使用协议。本数据集将每年更新。
