Vital statistics: births, marriages/divorces, deaths, pros: comprehensive, cons: limited risk factor data, not all fields are completed accurately. Administrative data: enrolment and eligibility info (e. g. kaiser permanente insurance, Medicaid coverage: claims information/managed care encounters, pros: large amounts of detailed data, covers pharmaceuticals, cons: often collected for billing purposes rather than public health.
