(CNN) The Trump administration has acknowledged that its proposed changes to the food stamp program could leave nearly 500,000 children without access to free school lunches.

The US Department of Agriculture released an analysis late Tuesday afternoon that showed the agency's proposed rule would mean nearly 1 million children would no longer be directly certified for free school meals based on their participation in the Supplemental Nutrition Assistance Program, or SNAP, the formal name for food stamps.

About half of those children would continue to be eligible to receive free meals because they come from families with annual household incomes of no more than 130% of the federal poverty level, or $33,475 for a four-person family in 2019.

However, another 497,000 kids would only be eligible for reduced-price meals since they come from households with annual income of between 130% and 185% of the federal poverty level, or no more than roughly $47,650. These students would have to pay a maximum of 30 cents for breakfast and 40 cents for lunch.

Another 40,000 students from families with higher incomes would have to pay for their meals.
