“Abortion surveillance is absolutely a critical component of what the CDC is currently doing,” Schwartz told lawmakers. “I also want to make sure that certain states are not conflating emergency services and hiding abortions in that emergency services case definition,” she continued. “We need to make sure we’re pulling out true abortions and making sure that we’re really having clear case definitions regarding abortions so the data is actually accurate.” There is no factual evidence suggesting that states are “hiding” or purposefully misreporting information about abortions to the CDC, HuffPost reported Thursday. The CDC’s data collection on abortion is currently voluntary, meaning that certain states, such as California, New Jersey, and Maryland, don’t report annual abortion numbers to the federal government.
