Datasets For Cleaning Practice – Specific Topics

Hi, I hope someone here can help – I am looking for a messy dataset for my assignment and I am hitting a wall.
Not as simple as just any set – the assignment is to find a clean one and a messy one and then join those on a common variable, then perform analysis. So these need to be somewhat related topics wise and include a common variable.
i would like to work on the subject on gender representation and I already have several clean sets with general demographic info but i just cannot find anything messy enough (this is still a beginner level so they don’t just want me to do standardisation etc but I need something that includes observations as variables, missing data etc). I was hoping to find something on gender representation in politics by country to then join to my clean sets by country variable. Any help much much much appreciated!!
