URGENT action is needed to stop the deaths of child pedestrians in deprived areas, it is claimed.
New figures show that eight children died on West Yorkshire's roads in 2004.
There were more than 1,380 child were casualties.
Campaigners from the End Child Poverty campaign and children's charity NCH said poorer children are among the most vulnerable.
Department of Transport figures show a nationwide 4% increase in child fatalities and the number of fatalities of cyclists of all ages by 18%.
George McNamara, policy adviser at NCH said: "It is a fact that a child living in a deprived area is more likely to die on the road than those living in more affluent parts of the country.
"Improving child road safety in West Yorkshire must be a priority for policy makers.
"It is essential that the Government works with local authorities, particularly in areas of high deprivation, and prioritises resources to make our roads safer for children."
ECP director Jonathan Stearn said: "We know from pilot schemes that by reducing car speeds and congestion and by making streets child friendly, rather than car friendly we can cut the number of children killed on the roads.
"These measures should be introduced in West Yorkshire without delay."
The report says children from the lowest social classes are five times more likely to die in road accidents than those from the highest social class.
Child pedestrians in the most deprived areas are more at risk and more than one quarter of child pedestrian casualties are in the most deprived 10% of wards.
Poor children are also more likely to live near main roads where there are few safe play areas, and to play in the streets especially in summer.
