I am trying to join a
.csv-file with als rates and zip3 values to a shapefile with zip3 values and then color the map based on the als rates.
This seems very simple and I have done similar maps before but I am having trouble with the field types. Whenever I import the CSV it makes all of the field types strings and I am not able to change them even using the refactoring toolbox. Then when I join them they are still strings and I am not able to style them using graduated symbols because they are not numerical.
Here is a link to the shapefiles and the csv that I am using: https://drive.google.com/drive/folders/1X26BXzrCtjSGuAPweH3HPiGshcfGaU6U?usp=sharing
I am using QGIS version 3.10
