Advantages of using official statistics

Easy to access and regularly updated
Provide trends over time to see impacts of social changes
Look at differences based on ethnicity, gender, sexuality, and religious beliefs to help spot inequality and diversity
Highly reliable as they are repeated often
Official statistics can become a starting point for lots of sociological research, particularly in examining inequality in contemporary society
There are practical issues with official statistics, such as the time it can take to interpret and analyze the large amounts of data, the data being out of date, and the definitions used not always aligning with what sociologists are looking for
Ethically, official statistics are quite sound, but they can be manipulated by governments to prove political or ideological points, which can negatively impact certain groups in society
Theoretical issues with official statistics

Interpretivists would suggest they are a social construction, as it is up to those in power to decide what actions or behaviors fit definitions
There are issues relating to 'dark figures' - actions or behaviours that are not reported or recorded anywhere through official channels
Marxist and feminist perspectives would suggest they can be manipulated to suit the needs of capitalism and the patriarchy
