About half would be a good guess. "Registered" means different things in different states. And the United States is made up of 50 states and each one of those states has it's own laws on how parties and primaries and registration are run.
In the 2012 National Presidential Election President Barack Obama received 49% of the males voting and 56% of the females voting. But that doesn't really suggest the make-up of 'registered' Democrats because lots of people who were Republican or Independent voted for Obama in the 2012 election.
A "National Democratic Party" or a "National Republican Party" is a misnomer in many regards. Those entities are made up of the representative of all of the state political parties. And although they both maintain rules and regulations and enforce them all of the rules are a creation of what the state parties want or don't want.
Registration is a function of the state law you are in. Registration is viewed differently in each state.
