Key Insight

This dataset reveals the marital status distribution of Singapore's residents across various age groups and ethnicities.  A clear trend shows a decrease in the proportion of single individuals as age increases, while married individuals constitute the largest group across most age brackets.  The proportion of widowed and divorced/separated individuals increases with age.  Ethnic variations exist, notably in the proportion of married individuals, suggesting potential cultural or socioeconomic factors at play.  The data could inform policy-making relating to family support, social welfare programs, and community planning.

Small Interesting Points of Note

There's a noticeable difference in the proportion of married individuals across ethnic groups, especially in the younger age groups.  Additionally, the number of widowed individuals increases significantly in older age groups, indicating life-cycle changes reflected in the data.
