Methodology:
This study employs a synthetic panel approach using nationally representative microdata from the Household Income Survey (HIS) for 2004 to 2022. The analysis computes bootstrap point estimates and standard deviations to examine poverty dynamics, vulnerability, and economic security, comparing three poverty line scenarios and three income group classifications to assess absolute and relative mobility.

Key Findings:

• Chronic poverty decreased significantly from approximately 22-28% of the population in 2004-2007 to 2-3% in 2019-2022. Poverty entry rates also declined.
• Economic security, defined as sustained income above a vulnerability line, increased across most groups. Headline poverty exit probabilities improved over time, though regional and ethnic disparities persist.
• Significant gaps exist across subgroups: Rural East Malaysia and East Malaysia Bumiputera groups face higher chronic poverty rates, higher poverty entry risk, and lower escape chances. Economic mobility appears higher in urban Peninsular Malaysia.
• Relative mobility analysis shows persistence in income distribution: About 9-12% remain in the poorest quintile, and 11-14% in the richest, indicating low interquintile switching over time.
• The findings highlight broad-based economic improvement but uneven progress, with rural East Malaysia lagging despite absolute gains reducing cross-group differences from earlier periods.
• Policy interventions, such as Covid-19 relief, contributed to better escape outcomes, but official poverty figures may differ due to changing poverty lines.
• Results depend on income thresholds; mobility trends vary across scenarios, emphasizing the sensitivity to definition choices.

Conclusion:
The period 2004-2022 saw substantial improvements in economic mobility and poverty reduction, driven by broad-based growth and support policies. However, relative positions of societal groups remain largely unchanged, with persistent regional and ethnic inequalities, particularly in rural East Malaysia. Economic security is higher in urban areas, and downward mobility increases for certain subgroups. The analysis underscores the need for targeted interventions to address disparities and support sustained mobility.
