HCHS variables
This variable is the sample design stratification variable used in statistical analyses as the stratum variable that is a combination of field center, Hispanic household proportion, and SES.

HCHS variables
The calibrated sample weight is the calibrated, trimmed, non-response adjusted reciprocal of a participant's probability of selection into the HCHS/SOL study. The trimmed, nonresponse adjusted sample weights were calibrated using first the 7-category Hispanic Background distribution and then the 12-category age group/gender distribution using the 2010 Decennial Census. This variable is used for analyses purposes only.

HCHS variables
The normalized sample weight is the overall normalized, calibrated, trimmed, nonresponse adjusted (household and person-level) reciprocal of a participant's probability of selection into the HCHS/SOL study. The base sample weights, i.e. the reciprocal of a participant's probability of selection into the HCHS/SOL study, were first adjusted by household-level and person-level non-response. The non-response adjusted sample weights were then trimmed using the selected average percentile that minimizes model MSE within each field center. All sample weights that fell above the selected percentile were trimmed to the selected percentile and the trimmed difference was evenly distributed among all of the non-trimmed sample weights. The trimmed, non-response adjusted sample weights were then calibrated using first the 7-category Hispanic Background distribution and then the 12-category age group/gender distribution using the 2010 Decennial Census. Finally, these calibrated, trimmed, non-response adjusted sample weights were normalized using the weighted mean divided by weighted standard deviation of the entire HCHS/SOL sample to normalize the expanded calibrated sample weights (WEIGHT_Final_Norm_Overall). This final sample weight variable is used for analyses purposes only.

HCHS variables
This variable is the self-identification with a Hispanic/Latino cultural group, based on a sub-cohort of participants 45+ years old, crossed by field center and grouped into categories.
Note: This variable was derived from race and was not asked as a separate demographic question. At the time of SHHS Visit 1, race and ethnicity were collected together in a single question. This variable was derived later on when the datasets were prepared for deposition in Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC).
Note from MESA Coordinating Center: It is recommended that Investigators make use of the terminology "race/ethnicity" when publishing or presenting variable race1c results (e.g. descriptive summaries, associations, ...). It has been noted that Chinese and Hispanic are not race groups, and that race itself is an ill-defined, non-scientific concept.

HCHS variables
The self-identification with a Hispanic/Latino cultural group allowed for selection of an 'other' designation. This variable groups the test responses of 'other' for variations of 'Dominican' so that undercounts do not occur for that group.
