Relating to the interaction between social and economic factors.
The socioeconomic status of a family can affect their access to education and healthcare.
Socioeconomic is formed from "socio-" (from Latin "socius", meaning companion or ally) and "economic" (from Greek "oikonomikos", meaning skilled in household management). The term combines these parts to refer to the social and economic factors that influence individuals and communities.
Think of 'socio-' as relating to companions or society, and 'economic' as relating to household management. This helps you remember that 'socioeconomic' refers to the interplay between social and economic factors.
