I've got some data about people in Bristol. I have about 75,000 records. Part of my dataset is each respondants age.
Aside from this, I have also downloaded census data for Bristol, which gives me the number of each in each age category i.e. 25000 people aged 1, 26000 people aged 2.... 916 people aged 100 etc.
What I'd like to try and do now, is to test how similar my own dataset is, in terms of ages, to Bristol overall. Can I give a figure which represents how 'representative' of Bristol?
Could someone talk me through how to do this please?
