- In an industrial society, families are primarily seen as units of consumption rather than production.

- Traditionally, families produced goods, especially in agrarian societies, but industrialization shifted much of the production role to factories and businesses.

- Families now mainly earn wages and spend money on goods and services, making them central to the consumption process.

- Production and profit are roles more associated with businesses and industries rather than family units in modern societies.
