To reach a conclusion, we first looked at the number of people wearing a mask in every state according to COVIDcast (data as of Feb. 14, 2021). This provides a sense of how many people are following what’s become a fairly basic hygiene measure. Then, we examined the most recent data on the percentage of hospitals in each state that met all of The Leapfrog Group’s hand-hygiene protocols*. Finally, we factored in WalletHub’s dental health index. The outlet used a number of data points—like the percentage of adolescents and adults who visited the dentist in the last year—to score states based on how well residents take care of their teeth, a key hygienic marker. WalletHub gave each state a score on a 100-point scale, with 100 representing the best dental health and 0 indicating the worst. Metrics on the number of showers taken per day per state or the number of cleaning products bought per state were unavailable, meaning our figures relied more on public health data. It’s worth noting that this could mean that less wealthy states, or those with worse-funded public healthcare, rank as “less hygienic.” Based on the data available, we gave each metric a weighted value before running them through our exclusive algorithm to see how each state scored on our 100-point scale Unhygienic Index. Overall, our results show that states in the Northeast are generally more hygienic, while states in the South and West seemed t0 struggle more when hygiene.

In those cases, you’ll see an “N/A.” We adjusted the algorithm to ensure that each state was scored fairly and accurately.
