Factors Determining Weight in Consumer Price Index Categories

In the Consumer Price Index (CPI), the weight of categories like food, housing, clothing, and entertainment is determined by various factors.

In the Consumer Price Index, the weight assigned to each category is influenced by the quantities of goods and services people typically purchase within that category. The weightage reflects the proportion of consumer expenditure that goes towards those specific items.

For example, the category of housing has the highest weight in the CPI, typically around 42%. This is because housing expenses, such as rent or mortgage payments, utilities, and maintenance costs, form a significant portion of overall consumer spending.

On the other hand, categories like clothing and entertainment may have lower weights in the CPI, as they represent smaller portions of consumer budgets compared to essentials like housing and food.
