What are the differences between a target market and a demographic?
In short, demographics should be considered for defining your target market.
Your target market consists of your current customers and potential new customers. Businesses usually focus their marketing on their core customers - their target markets. Target markets share common characteristics that help shape the message for marketing communications. One common characteristic of target markets is a similar demographic. So, demographics can help you define your target market.
Demographics can include age, gender, location, marital/family status, income, occupation, education, etc.
