1) Nature of commodity: Necessaries have less than unitary elastic demand whereas, luxuries have more than unitary elastic demand.
2) Time period: Demand is inelastic in short period but elastic in long period.
3) Price level: elasticity of demand will be high at higher level of the price of the commodity and low at lower level of price.
4) Diversity of uses: Commodities that can be put to variety uses have elastic demand. On the other hand, if a commodity has only few uses, its demand is likely to be less elastic.5) Habit of consumers: Goods to which consumers become habitual will have inelastic demand.

Answer:

There are several factors that affect how elastic (or inelastic) the price elasticity of demand is, such as the availability of substitutes, the timeframe, the share of income, whether a good is a luxury vs. a necessity, and how narrowly the market is defined.
