If income elasticity is positive, then it is a normal good. Otherwise, it is an inferior good.

What are the types of income elasticity of demand?
Income elasticity of demand(EY):Income elasticity of demand measures the relationship between a change in quantity demanded and a change in income. Income elasticity of demand measures the degree responsiveness or reaction of the demand for a good to a change in the income of the consumer. It is calculated as the ratio of the percentage change in demand to the percentage change in income. In other words, it is defined as the rate of percentage change in quantity demanded resulted from percentage change in consumer's income. For example, if, in response to a 10% increase in income, the demand for a good increased by 20%, the income elasticity of demand would be 20%/10% = 2.Types of Income elasticity:i. Zero Income Elasticity of DemandZero income elasticity of demand is that in which quantity demand for a commodity remains constant to any change in income of the consumer. The value of the zero income elasticity is zero. It can be found in case of neutral goods. Graphically it can be explained asIn the graph, quantity demand is measured in X-axisand income is measured in Y-axis. DD is the demandcurve which is parallel to Y-axis implying that nochange in quantity demanded to any change inconsumer's income. Income is varying from Y1to Y2 and Y2 but quantity demand remain thesame quantity at Q1.ii. Positive Income Elasticity of Demand(EY>0)Positive income elasticity of demand is that in which increase in consumer's income leads to increase in quantity demanded and vice-versa. The numerical value of positive income elasticity is always greater than zero which may be greater than(for luxurious goods) or equal (for normal goods)or less than(for necessity goods) unity i.e. 1. For example, when consumers become reach or increase their income then they spend more on luxurious goods. On the contrary, consumers purchase less quantity of luxurious goods if their income decrease or they become poor. It can be further explained with the help of following figureIn the given figure, DD is the demand curve which is positivelyslopped. This demand curve implies, when consumers incomeincreases from Y1 to Y2 as in figure then consumer demandedmore quantity i.e. increases quantity from Q1 to Q2 accordingto figure.i. Negative Income Elasticity of Demand(EY
What is the difference between price elasticity and cross elasticity of demand?
Cross price elasticity of demand measures how much demand of one good, say x changes when the price of another good, say y changes, holding everything else constant. For example, you can measure what happens to the demand of bread when the price of milk changes. The cross price elasticity is calculated as the percentage change in the quantity demanded of good x divided by the percentage change in the price of good y. If the cross price elasticity is negative, then we call such goods Complements (example: pizza and soft drinks -- they are consumed together). If the cross price elasticity is positive, then we call such goods Substitutes (example: pizza and burgers -- you usually consume either or). The income elasticity of demand measures the change in the quantity demanded of some good, when the income changes, holding everything else constant. For example you can measure what happens to the demand for expensive red wine when income increases. The income elasticity is calculated as the percentage change in the quantity demanded of the good divided by the percentage change in income. If the income elasticity for a good is positive we call them normal goods. It can be between 0 and 1, and we call it income inelastic demand for goods such as food, clothing, newspaper. If it is above 1, we call it income elastic demand. Examples are the red wine, cruises, jewelry, art, etc. If the income elasticity is negative, this means that as income increases, the quantity demanded for those goods actually decreases, we call those goods inferior goods. Examples are "Ramen noodles", cheap red wine, potatoes, rice. etc.
What happens to demand for normal and inferior goods when there is a decrease in your income?
the demand for inferior goods varies inversely with income. If your income rises then the demand for rice will decrease. the demand for normal goods varies directly with income. If your income rises the demand for these goods will rise as well. Most goods are normal goods ie, cars, new homes, furniture, steaks, and motel rooms. Economics, Stephen L Slavin 10e
What happens to demand if income increases and commodity is normal?
Demand also increases.
Demand curve of a giffen good?
A Giffen good is a good whose consumption increases as its price increases. (For a normal good, as the price increases, consumption decreases.) Thus, the demand curve will be upward instead of downward sloping.A giffen good has an upward sloping demand curve because it is exceptionally inferior. It has a strong negative income elasticity of demand such that when a price changes the income effect outweighs the substitution effect and this leads to perverse demand curve.
Definitions of income elasticity of demand?
income elasticity can be applied in the intersection of market demand and supply. when there is income inequality people with less income get to buy less goods than they would have wanted this affects the suppliers who will have to reduce their goods to be supplied.

Demand also increases.
How does consumer income affect the demand for normal and inferior goods?
A consumers income can affect their demand for most goods, for normal goods if the consumers income increases then there is a demand for more normal good, but a fall in income would cause a shift to the left for the demand curve, this shift is called a decrease in command. For inferior goods, an increase in income causes demand for these goods to fall, inferior goods are goods that you would buy in smaller quantities, or not at all, if your income were to rise and you could afford something better.
Demand curve of a giffen good?

It has a strong negative income elasticity of demand such that when a price changes the income effect outweighs the substitution effect and this leads to perverse demand curve.
How does consumer income affect the demand for normal goods?
A good that decreases in demand when consumer income rises; having a negative Income increases will thus affect the consumption of these goods.
When income increases the demand for this type of good decreases is what?
normal food
When income increases the demand for this type of good decreases is called what?
normal food
If the demand for a good falls when income increases the good is call a good?
Normal good
Is income held constant along the demand curve?
Yes, an increase or decrease in income will cause a shift in the demand curve right or left depending on if the good is inferior, normal, or superior
