Key Insight

The data reveals significant variations in household expenditure patterns across different income quintiles in Singapore during 2007/08. Lower-income households allocate a larger proportion of their budget to essential food items like rice and bread, while higher-income households spend more on discretionary items such as meat, fish, and alcoholic beverages. This highlights income inequality's impact on consumer behavior and spending priorities. The data is limited in that it only reflects expenditure from 2007/08 and may not represent current trends. Missing values (indicated as "na") prevent a more precise statistical analysis.

Small Interesting Points of Note

The highest percentage of expenditure across all income quintiles is consistently on "Food and Non-Alcoholic Beverages." There's a clear trend of higher-income households spending proportionally less on staple foods and more on higher-value protein sources like meat and seafood.

Methodology

• Data was obtained from the provided API endpoint, focusing on the 'records' field.
• Percentage values were parsed and analyzed to understand expenditure patterns for each income quintile.
• Observations were made regarding the relative expenditure for various food and beverage categories across income brackets.
• Due to the presence of numerous "na" values, a complete statistical summary was not possible. Qualitative analysis of trends dominated over quantitative statistical summary.

Footnotes

Some data points were missing (represented as "na" in the original dataset) and were excluded from the numerical analysis. This limitation affects the overall conclusions drawn.
