-The Long-Term Care Aggregated Dataset is a collection of insurance data for 'incidence' and 'termination' categories.
-It is compiled from Long Term Care insurance policies data, providing insights into trends and patterns in insurance claims
-and terminations. This dataset can be used for actuarial analysis, risk assessment, and to inform insurance product development.
