Final answer:
The period an association must exist to be eligible for group insurance is not specified here and can depend on various factors such as the group's risk profile and the insurer's policies.

Step-by-step explanation:
To determine the eligibility for group insurance, the criteria may not only be based on how long an association has been in existence, but also on other factors such as the size of the group, the risk profile of group members, and regulatory requirements, which can vary between jurisdictions.
Risk management and the need for actuarial fairness require that the group shares similar risks, ensuring that There isn't an imbalance between high-risk individuals and lower-risk individuals within the insurance pool. The history and stability of the group might impact the perceived risk by insurers, with established associations often seen as more stable and potentially qualifying for insurance benefits sooner.
In the United States, the Affordable Care Act addressed the accessibility of health insurance, expanding eligibility for Medicaid and creating state-sponsored health exchange markets to mitigate the issue of adverse selection in health insurance markets. However, the specific period an association must have existed to be eligible for group insurance isn't detailed here and could be subject to specific insurance company policies or state regulations.
