What is the expected growth rate for mobile data in the US market 
ll discuss the expected financial impact of this agreement later in the call.
Turning back to our focus on generating superior long-term returns, one of our core principles of our strategy is to remain U.S. only because we believe it represents the best market for wireless infrastructure ownership since it has the most attractive growth profile and the lowest risk. And we believe this dynamic of higher growth and lower risk will continue into the future, which is why we expect our U.S-based strategy to drive significant returns for our shareholders.
Starting with the higher growth we see in the U.S., the demand for our shared infrastructure offering across towers, small cells and fiber is tied to the robust demand for mobile data in the U.S., which continues to increase by more than 30% annually. Because the outlook is so compelling, the U.S. wireless market continues to attract a disproportionate amount of global capital investment. This is likely due in part to the fact that the durability and scale of wireless data growth in the U.S. has repeatedly outperformed expectations. I remember fielding questions from investors and analysts nearly a decade ago, trying to understand why we were not expanding our tower business and the less established international markets that offer the promise of outsized growth to compensate for the outsize risk.
The core set of assumptions underpinning that line of questioning included a view by many that it was inevitable that U.S. growth rates would flow. Leading to a desire to augment that growth by investing in international wireless markets, that hopefully would develop the same key set of fundamentals over time, that has made the U.S. market so successful for decades. We didn't buy into that argument at the time and sitting here today on the doorstep to 5G, we reach a similar conclusion that the U.S. is still among the highest growth markets for wireless infrastructure.
Importantly, in a shared infrastructure business with long-term investment horizon, we have benefited from these superior growth rates while avoiding the risks associated with investment opportunities in less established international wireless market. These risks can have a meaningful impact on long-term returns and many have materialized in recent years, including the outsized churn due to less favorable industry dynamics relative to the U.S., sustained foreign currency devaluation that results in revenue churn, and disruptive social or governmental environments in less developed countries. Because we believe the U.S. has both greater potential for growth and lower risk, we are focused on growing cash flows on our 40,000 towers by providing access to existing and new customers that are building 5G wireless network.
We are investing in new small cell and fiber assets that our customers need for their wireless networks, which we believe increases our ability to capitalize on the 5G growth trends in the U.S., and we are developing new capabilities and offerings that will leverage our existing assets to drive innovation. And we believe we'll further extend our growth opportunity, such as CBRS and edge computing. I believe that Crown Castle offer shareholders an unmatched opportunity to benefit from the launch of 5G wireless networks in the U.S.
In the near to medium term, we expect to deliver outsized AFFO per share growth of 11% this year, as we translate this increasing 5G activity in the very attractive bottom-line growth. We expect to once again deliver the highest tower revenue growth rate in the U.S. among our public tower peers in 2021. And our customers are affirming the value we bring with our comprehensive portfolio of shared wireless infrastructure assets by entering into long-term agreements to access those assets. Longer term, we believe Crown Castle provides an exciting opportunity for shareholders to potentially compound double-digit total returns over a long period of time with a high-quality dividend that currently yields 3% and that we expect to be able to grow 7% to 8% annually.
