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.
