1. Real estate: During a recession, the real estate market usually takes a hit because people can't afford home prices. When the real estate market undergoes a correction, home sales drop, investment is scaled down, home prices fall, and various real estate and construction development projects are abandoned.

2. Finance: during recession, banks and financial institutions may be at risk, due to poor economic conditions, people's demand for borrowing falls and users continue to grow, so that the source of bank profits is greatly affected.

3. Retail: During a recession, the purchasing power of most people decreases and consumer spending is reduced, which can have a major impact on the retail sector. The average consumer has been one of the key drivers of U.S. economic growth for decades. Their reduced purchasing power means retailers will have to reduce inventory and lower prices to attract consumers.

4. MANUFACTURING: Manufacturing and industrial production were hit hard during the recession as people reduced their need to consume groceries and other goods. This led to factory shutdowns and layoffs which had an impact on the livelihood of manufacturing employees.

5. Service sector: during a recession, people usually cut down on unnecessary expenditures such as travel and services such as food and beverage. This will have an impact on the service sector, leading to a decline in business and employee layoffs.

Overall, recession affects all aspects of the economy, hitting various sectors, but the relevant program is the relief measures taken during the downturn, as the short-term banking system system is saturated, leading to measures to force liquidity.
