expectancy.org
There’s substantial private money in ageing research now, and the organisations forming around it need names that sound scientific rather than promotional. This one does the work without trying.
Expectancy carries serious analytical weight. Life expectancy is the headline measure of population health and the number driving pension policy, insurance pricing and development comparison, making it among the most cited statistics anywhere.
The name suits a demographic research organisation, a public health body, an actuarial resource, a longevity research group, or a data project publishing population statistics. The .org is what almost every organisation in that space uses and it signals research rather than product.
A second reading exists in psychology, where expectancy theory is a well-established framework in motivation research.
One word, precise meaning, no plural problem, naming something every country measures.
The name is listed. Offers welcome.
