Number of substitutes available

more available substitutes tend to make demand for a good elastic; fewer available substitutes tend to make demand for a good inelastic

number of substitutes available, luxuries versus necessities, the percentage of income spend on the good, and time

The percentage of income spent on the good

the demand for goods that take a large percentage of income tends to be elastic; the demand for goods that take a relatively small percentage of income tends to be inelastic

Luxuries versus necessities

the demand for luxuries tends to be elastic; the demand for necessities tends to be inelastic

Time

the less time you have to respond to a price change in a good, the more likely it is that your demand for that good is going to be inelastic
