In general, aggregate demand depends only on prices and total income and not on income distribution.

Aggregate demand can be influenced by income distribution because changes in how income is distributed across different groups in the economy can affect overall spending patterns. For instance, if more income is concentrated among wealthier individuals, who have a lower marginal propensity to consume, aggregate demand could be lower compared to a more equitable income distribution that supports higher consumption levels among a broader base of the population.
