One of the biggest pieces of data going into this is the probabilities. Most of what I have found are the data provided by the insurance companies:
1) 70% of all people over 65 will eventually need long term care. Note this would mean "some type of LT care" like it could be an aid coming to the house not necessarily in a nursing home. The scary monthly cost of course.
2) Most nursing home stays are < 90d
3) Most policies have an exclusion time of 90d. With the confusing "service days" or "calendar days", and qualification of 2 ADL activated. You have other people deciding if you will collect and oh... if you cannot collect you have to pay the cost anyway until the exclusion is over. Which seems like you need a pot of money anyway to fund these sporadic unpredictable episodes. I am not sure if the 90d exclusion "resets" on every episode or not. Personal experience with both sets of parents that is what actually mostly happens, a series of shorter visits, followed by perhaps a 3 month final visit at death.
4) One piece of stated information on probabilities on nursing home care durations:
22% of men, 36% of women > 1 year stay
8% of men, 15% of women > 3 year stay... I also found it stated as 1 in 20 chance of > 2 yr.
2% of men, 7% of women > 5 year stay
Note I think these numbers are people that actually have any nursing home stay at all which is 40% of the population. So I am unsure for example the > 3 year stay, if one multiplies 0.4*0.08= 3.2% chance a man in the general population would have a stay of > 3years?
Question: Does anyone that has researched this heavily have a source that talks about the real numbers of...
- General population, men and women.
- What is the probability of nursing home stays > 90 d, > 1 year, > 2 years, > 3 years, >4 years?
- Also it would be interesting if someone had insurance company data of... for a couples policy bought at age 60, how many people bought these LTC policies, how many people actually collected any money at all ever, how many collected for 12 months, 24 months, 36 months, etc.... insurance companies would not state that

I personally would like to have had a policy that is catastrophic. I pay the first 3 years and insure for a cheaper policy for a really long term stay, but that does not seem to be readily available.
