Methodology
*The Longevity Preparedness Index was conducted online and by phone interview in English, sourced through the NORC AmeriSpeak Panel. The sample was a US representative sample
comprised of 1,307 Americans, aged 18 and up, with specific oversamples of Non-Hispanic Black panelists, Hispanic panelists, and Non-Hispanic Asian American and Pacific Islander
panelists to ensure adequate sample size for sub-group analysis. During analysis, survey responses were weighted to represent the US population. Survey data were collected from May
14th, 2025, to June 5th, 2025, with a median survey length of approximately 25 minutes per respondent.
LPI scores can range from 0 (not at all prepared for longevity) to 100 (completely prepared for longevity). The overall LPI is composed of 8 domains. Domain scores are each calculated
independently and can range from 0 to 100. All eight domain scores were averaged to calculate the overall LPI score. Eight to 26 unique survey items are used to represent preparedness
for each domain. Each domain captures positive behaviors toward longevity preparedness and awareness of the importance of a domain. Missing data were handled by imputation based on
modal scores by age, gender, and income. Based on respondents aged 65-85, survey items were weighted to indicate their contribution to preparedness within a domain. Items with low
weights were removed from score calculation. Behavioral scores (weight 75%) and awareness responses (weight 25%) were combined to create a domain score that can range from 0 to
100.
The Longevity Preparedness Index was developed in collaboration with MIT AgeLab and funded by John Hancock. John Hancock provided financial support for the research but did not
