The line chart illustrates the proportion of weekly income that families in a particular country allocated to five different categories in two years: 1985 and 2015.
Overall, there was a noticeable shift in spending habits over the three decades, with a clear trend towards increased expenditure on housing and transport, while the proportion spent on food and other goods decreased. Recreation saw a modest rise.
In 1985, the largest share of income, 32%, was spent on food, followed closely by housing at 28%. However, by 2015, housing had become the dominant expense, rising to 35%, whereas food expenditure dropped significantly to 22%. Transport costs also increased during this period, moving from 15% in 1985 to 20% in 2015.
Regarding the remaining categories, recreational spending experienced a slight increase from 10% to 13% over the 30-year period. Conversely, the 'other' category saw its share of income fall from 15% in 1985 to just 10% in 2015.
