Trends in Aged Care Star Ratings Visualised (Q4 FY23-24 update)

Note

The original version of this article was posted on June 25, 2024.

In this article I share interactive graphs that allow readers to explore trends in Australian aged care star ratings grouped by various variables. Most variables are directly taken from the quarterly star rating extracts, but provider size had to be derived, and regionality was modified by grouping MM3-5 and MM6-7. Additionally, service sizes for Q3 FY22-23 were missing, so I imputed these values based on data from the previous and subsequent quarter. I have included a description of each variable in Table 1. When grouped by ‘nothing’, all services are considered as a single group. By default, points are connected with a Catmull–Rom spline.

quarters_in_order = ["Q2 FY22-23", "Q3 FY22-23", "Q4 FY22-23",
