Oxfam is comparing statistics on child mortality and child poverty with increased military spending figures as part of a campaign to raise awareness of international development issues.
Oxfam wants the world's richest countries to increase the amount of funding they give poorer nations to 0.7 per cent of national income. If the US did this, it would equate to a quarter of the sum pledged by president Bush for military spending.
An Oxfam spokeswoman said: "Making those kind of comparisons helps people get their heads around huge figures, and understand the world's priorities."
Nearly 60 million children in the developing world will die during the next 15 years unless aid levels rise, according the charity's new report.
The report, Last Chance in Monterey, was published to coincide with the run up to this week's UN summit on international aid in Monterey, Mexico.
