LinkedIn topped the 100 million member milestone, and the professional networking site marked the occasion with two blogs posts and an infographic (after the jump).

Highlights from the post by CEO Jeff Weiner:

We’re now growing at roughly 1 million new LinkedIn members every week, the equivalent of a professional joining the site at faster than one member per second.

So, what does all this growth really mean? We’re making great progress toward our ultimate goal: to connect all of the world’s professionals to make them more productive and successful.

We’re also rapidly growing our network globally — our site is currently used in more than 200 countries and territories around the world, with more than one-half of our users coming from outside of the United States. You can now connect just as readily with someone in Sao Paulo or Singapore as you can with your colleagues in San Francisco, London, or New York. You no longer have to live in the same city — or even the same country — to build and strengthen relationships that can help you succeed and grow professionally and fundamentally transform the trajectory of your career path.

We want to thank all of you, our 100 million members, for making this happen. Your experiences, connections, and shared knowledge are what make LinkedIn so powerful to each and every one of us.

Best of all, we’re just getting started. Here’s to the next 100 million members.

Highlights from the post by senior data scientist Scott Nicholson:

While our early adopters from May 2003 could have a (huge!) party, it would be a bit difficult for all 100 million of us to physically get together and celebrate. Turns out we could do it in a Boeing 747, but in order to do so, we’d have to shrink our bodies down to the size of 0.96-inch (24.4-millimeter) diameter gumballs!

In celebration of the occasion, our team of stellar Data Scientists pulled together some fun stats about our members and their professional profiles:

• 56,800 miles (90,900 kilometers): length of the conga line formed by all of our members celebrating our latest milestone. That is equivalent to 9.76 round trips on the road between San Francisco and New York City!

• 74 profiles with Elvis impersonator listed as a position

• 1.3 billion-plus connections between our members

• 1,091 profiles with chocolatier listed as a position
