The cost-of-living crisis has become a pressing concern for many Australians. Essential items such as food and housing have seen unprecedented price hikes.
To explore these changes, this project analyses Consumer Price Index (CPI) data from the Australian Bureau of Statistics
The All Groups CPI represents average price movement across all household spending categories.
Housing CPI reflects costs influenced by mortgage rates, rent, interest rates, and urban expansion.
The steep rise post-2000 highlights the housing affordability crisis, with volatility during the GFC and COVID-19 recovery. The density plot shows broad spread in housing CPI values, indicating unequal impact across regions or housing types.
Food prices are sensitive to weather events, international supply chains, and agricultural yields.
After 2020, food CPI surged, with the boxplot showing higher variability, pointing to instability in food systems - possibly due to pandemic disruptions and global shocks.
This slide presents a side-by-side comparison of CPI trends across three key categories: All Groups (overall inflation), Housing, and Food. It highlights how price patterns have evolved over time.
Since 2020, Housing and Food CPI have risen faster than the overall index, highlighting their role in driving inflation and household cost pressures.
This snapshot highlights the latest 2024 CPI values across key spending categories. The bar and dot plots provide a clear comparison of areas most impacted by inflation.
Housing’s share in overall CPI has grown significantly over time. This stacked view reveals how housing dominates recent CPI shifts, followed by food -indicating core household expenses are becoming increasingly expensive.
The 2024 snapshot offers a clear view of inflation in Australia, with housing leading and food close behind—highlighting the rising pressure on everyday essentials.
Housing CPI leads all categories, reflecting the continued pressure on household budgets in 2024. Food follows, reinforcing the cost-of-living burden across basic needs.
