I would like to ask for advice regarding recreating a logistic regression model (please see the picture attached). I am working with household level data (English Housing Survey) and on the top of the already present household-level variables, I would like to construct area-level variables (such as regional unemployment rate % or barriers to housing [based on the Index of Multiple Deprivation indicator]). So my problem is that I am not sure how to construct this variable, percentage/index is technically a number but as it is going to be the same number (a kind of 'category'?) for each region then should it not be a categorical variable?

I would really appreciate help, I've been struggling with this for a while
