Every week the news about Obama’s presidential library gets better.

We saw the designs recently; and now, a new Deloitte report reveals that the economic benefit to Chicago will be even better than we all thought, DNAinfo reports.

The Obama family plans to build the library on Chicago’s South Side, in the Jackson Park neighborhood.

Besides bringing Obama-era artifacts and documents to the South Side, Deloitte reports that the museum is going to inject $177 million per year into South Side businesses.

And for Chicago and Cook County (the county the city resides in) at large? An additional $69 million, meaning that the Obama Presidential Center will net Cook County $246 million more per year than it is raking in now.

That’s like four Barack-Michelle book deals! That’s a lot of money!

Here’s an even bigger, even better figure: $3.1 billion. Yes, billion with a “B.” That’s the amount Cook County is expected to take in within the first 10 years of the center being open.

Allow us to throw some more excellent numbers at you.

4,945 jobs will be created during the construction of the 225,000 square feet facility; those workers will take home a combined $296 million to their families.

And even though those jobs won’t be permanent, the jobs the center creates will be — all 2,536 of them.

And for those who fear that those jobs will go to gentrifiers or to Obama donors from Chicago’s North Shore, old 44 promises that that won’t be the case. 80 percent of the library’s employees will be from Chicago’s South Side.

One more set of numbers that all Chicagoans will love: the number of tourists expected to come into the city just to see the Obama Presidential Center. 

Deloitte estimates the number will fall somewhere between 675,000 to 760,000 visitors per year.  And that’s in the years following the initial opening — the firm thinks that tourist numbers will be even higher the first year due to people wanting to come see the center while it is still new.

All in all, good news for Chicago, still reeling from the loss of $2 billion in revenue from the special-interest derailed Lucas Museum, and for a cash-strapped Illinois.
