For each HRMS round a stratified random sample of adults ages 18-64 is drawn from the KnowledgePanel, a probability-based, nationally represented Internet panel maintained by Ipsos. The approximately 55,000 adults in the panel include households with and without Internet access. Panel members are recruited from an address-based sample frame derived from the United States Postal Service Delivery Sequence File, which covers 97 percent of United States households. The HRMS sample includes a random sample of approximately 9,500 nonelderly adults per quarter, including oversamples of adults with family incomes at or below 138 percent of the federal poverty line. Additional funders have supported oversamples of adults from individual states or subgroups of interest. However, the data file only includes data for adults in the general national sample and the income oversample. Beginning in the first quarter of 2015, the HRMS shifted from a quarterly fielding schedule to a semiannual schedule.

针对每一轮HRMS调研，研究人员均从益普索（Ipsos）维护的概率抽样全国代表性互联网面板KnowledgePanel中，抽取年龄介于18至64岁的成年人分层随机样本。
该面板包含约55000名成年人，其招募来源涵盖具备互联网接入与未具备互联网接入的美国家庭。
面板成员通过基于美国邮政服务投递序列文件（United States Postal Service Delivery Sequence File）构建的地址抽样框招募而来，该文件覆盖了97%的美国家庭。
HRMS每季度的抽样样本包含约9500名非老年成年人的随机样本，其中额外超额抽样了家庭收入处于或低于联邦贫困线138%的成年人群体。
另有其他资助方支持了针对特定州或目标研究子群体成年人的超额抽样工作。
但最终的数据文件仅收录了全国通用样本与收入超额抽样群体的成年人相关调研数据。
自2015年第一季度起，HRMS的调研实施周期从每季度一次调整为每半年一次。
