[Marvel] What are/were the demographics of SHIELD/Hydra?

What percentage of SHIELD were Hydra? How many of both sides survived the unmasking (in winter soldier)? How much money did they have?

You might want to look up Agent Coulson and his team to get an idea of where SHIELD stands following the emergence of HYDRA.

But to give you a little overview, both organizations were pretty badly hit in the wake of the Helicarrier launches. A huge amount of SHIELD agents were killed by their former friends when HYDRA emerged, and many of those who weren't found that what remained of SHIELD wasn't worth serving any more. Some, like Maria Hill, went to work in the private sector, while others just took the opportunity to retire. Certain high security compounds became totally sealed off and were able to make it through unharmed, but others, such as "The Fridge," where a number of highly dangerous powered individuals were held, were compromised and the prisoners allowed to escape. Some of those compounds that made it through eventually splintered off into separate groups, like Gonzalez's "SHIELD" which borrowed the name of its parent organization.

Coulson was appointed to Director of what remains of SHIELD, and he's done a fantastic job rebuilding the organization... but it's still small. Very small. They do not have the reach or the resources to perform the kind of feats we saw them doing in prior incidents. It took basically all of SHIELD's resources to reactivate the old helicarrier, as you no doubt recently saw. Running short on man power has been a huge problem, as a lot of former agents just have no interest in returning to SHIELD, and Coulson still doesn't have a lot of trust after his apparent death. As a result, he's been forced into doing some things that the old SHIELD would never have considered, like hiring freelancers and putting together teams of superpowered people who might otherwise have ended up on The Index. Still, SHIELD is surviving, and arguably it's been a real rebirth in the wake of the Winter Soldier incident; they're no longer as big brother-y, and have reaffirmed their goals in protecting humanity.

HYDRA started off in a very strong position, having seized so many valuable assets from SHIELD, but they've suffered a lot of setbacks lately. Almost all of HYDRA's leadership has been taken out, and Baron Strucker was one of the last remaining. But HYDRA is nothing if not persistent, so only a fool would say we've seen the last of them. Cut off one head, and all that...
