Why is the catering business in demand right now?

The specific reason for catering being in demand would
vary depending on where you are living.  However, the general reasons for an increase in
the demand for catering are somewhat similar in all
places.

First, the demand for catering is likely to go up
as people become wealthier.  As they do, they are able to afford more in the way of
luxuries.  Catering is surely a luxury and therefore increased consumer income would
lead to increased demand for it.

Second, if people's lives
are becoming busier, catering might be more necessary to their lives.  If they are too
busy working, then they might not be able to do as much cooking for themselves.  This
may be especially true as women enter the workforce.

So two
major factors that would increase the demand for catering would be higher incomes (so
more people can afford it) and busier lives (so that more people need
it).
