Possibly 40 or under, married or single, newly married, urban
Many of us, myself included, struggle with that question: identifying and finding our target market. But here are a couple of suggestions:
1. If you have a facebook page, on the new style you can click on the 'big' like button and it will give you stats on the age group most often visiting your page, as well as demographic.
2. Image your ideal customer (male, female, both, household with children, age group, discretionary income, etc.) and write your business plan based on that. Once you have enough selling stats, you can adjust your plan or create more to that group.
Congrats on doing a business plan.\! I have yet to do it. Maybe that's what's missing in sales:):)
