For you and colton as well: Those numbers are all wrong. The LDS church systematically over reports growth and underreports loss.
Let's look at membership in Brazil. In 2010 the church claimed 1,138,740 members in Brazil. But in the 2010 census only 225,695 Brazilians claimed they were LDS. 913,014 members are missing! What gives?

The LDS church is very "optimistic" in figuring official membership numbers. It assumes 100% retention rates. Once you are counted as a member you are a member for life. And judging by the low death rates, members don't die as often as the rest of the population.
That doesn't mean the church doesn't know how many members are showing up to church, they are meticulous record keepers. Head counts are performed and quarterly reports are made. But these actual numbers are not reported to the public. They are a secret.
Let's take the numbers reported on April 6, 2013. Official membership was reported up by 341,127 to 14,782,473. The "increase in the children of record" is 122,273 and new converts are 272,330. (Mormon children are typically baptized at age 8, so a new "child of record" is a child of a member or a convert that hasn't been baptized yet.)
So are there any subtractions? The gross increase is 122,273 + 272,330 = 394,603. Difference between net and gross increase is 394,603 - 341,127 = 53,476. Even if we assume the entire subtraction is due to death, the death rate is at MOST 3.7 deaths per 1000. Compare that to the 8.4 and 8.3 deaths per 1000 for the U.S. and World respectively.

This has been going on for decades, and the LDS assumptions about its own death rates lead to a constantly increasing gap between the "real" number and the reported number even if we assumed retention rates were truly close to 100% as the church treats all former members that haven't officially resigned membership as current members.
Reality is retention rates will never be 100%. Only a fraction of these increases are keepers. Some older studies suggest 34% of the members born in the church will leave, while only 25% - 50% of the converts will stay for the first year. 80% of members will leave the church for at least 1 year.

Only the deaths of active members are reported by wards and branches to church headquarters. The church doesn't reveal numbers for resignations or excommunications.
The result is that the church over reports its gains and under reports its losses year after year. Over time the errors keep accumulating.
Sociologists have estimated that the self identifying membership is about 5 million. At 5 million the LDS church doesn't even rank with Jehovah's Witnesses or Seventh Day Adventists in numbers (Both of those churches use participation/attendance to determine their numbers.)

If you count only active members, there is a strong argument that church membership peaked some time ago, is aging demographically, and is an institution on the decline numerically.

I think the rate is closer to 30% and shrinking of whatever the church is reporting.
