Two weeks ago I looked at the correlation between the percentage of residents over the age of 66 in the county with the percentage of total county deaths in a nursing home and the case mortality rate in the nursing home.  This week I'm looking at the the additional variables of the % of the county in a rural area and the median household income in the county.  Of these, the relationship between case mortality and median income was the strongest accounting for 14.9% of the variability in the rates.


While this is a relatively weak (though significant) positive correlation there is a stronger correlation between that may moderate this relationship.  There a stronger relationship between % rural and % over the age of 66 of 0.62 (seen below).  Both of these have a relatively strong negative correlation of -0.49 and -0.48 with median household income respectively.    


The % over the age of 66 has a stronger positive correlation with the case mortality in the county (0.33) that it does with case mortality in a nursing home (LTCF) (-0.30 which is smaller in absolute value than 0.33).  This suggests that the elderly who live in more rural counties are more likely to die outside of a nursing home from corona virus.  The more rural and more elderly counties are also more likely to have lower incomes.
