Spanish is spoken by over 500 million people worldwide, making it the second most spoken language after Mandarin Chinese. Its popularity is rapidly increasing, and by 2050, the number of Spanish speakers is expected to reach 600 million. Spanish is also the second most studied language globally—in 2015, more than 21 million people were learning it as a second language. Within three generations, it’s estimated that 10% of the global population will be able to communicate in Spanish.
