We query HIBP with emails from the Florida voter registration database to estimate how often people's data has been breached. 83.9% of people have had their data breached at least once. The mean number of breaches per email is 6.2 and the median is 5. The average number of serious breaches, e.g., breaches where sensitive data like audio recordings, drug habits, photos, etc., associated with an email is 3.6; the median is 3. Given that data from only a small sliver of breaches are public and given that these breaches are related to one email (people often have multiple addresses), the total number is likely much higher.

The median number of breaches rises sharply from 2.5 to over 6 between 18 and 45 years before steadily declining to 3. This trend may reflect a combination of things: 1. total number of online accounts (which plausibly increases with age till you reach people who were too old to sign up for too many services), 2. digital savviness, which may be greatest among the youngest. (Winsorizing doesn't change the pattern much.)
The differences across sex and race/ethnicity are not very stark. The difference between the median number of breaches for men and women is 0 and the 7th percentile is 1. For race/ethnicity, NH White, NH Black, and 'Other' have a higher median (5) than other racial groups (4).
