The pie charts compare the proportions of people falling into three distinct age groups in Yemen and Italy in two different years.
It is clear that Italy had the older population in the year 2000, and that the same is predicted for the year 2050. The population of both countries are expected to age over the fifty-year period.
In the year 2000, just over half of the population of Yemen was aged 14 or under, while most Italians (61.6%) fell into the 15 to 59 age group, and only 14.3% were children under 15 years of age. People aged 60 or over accounted for almost a quarter of the Italian population, but only 3.6% of the inhabitants of Yemen.
By 2050, the proportion of children under 15 is predicted to drop in both countries, most noticeably in Yemen where the figure is expected to fall by 13.1%. On the other hand, the figures for elderly people are expected to rise, by 2.1% in Yemen and massive 18.2% in Italy. Finally, it is anticipated that the 15 to 59 age group will grow by around 10% in Yemen, but shrink by around 15% in Italy.
