Today, around 60,000 Sorbs live in Germany, about 40,000 in Saxony and 20,000 in Brandenburg. Since national affiliation is not officially recorded in Germany, and identification with the Sorbian nationality is voluntary, the exact number is only an estimate. The number of active Sorbian speakers is likely lower. Unlike Upper Sorbian, Lower Sorbian is considered critically endangered. According to projections, around 7,000 people actively speak Lower Sorbian, which could become extinct within 20 to 30 years, while around 13,000 speak Upper Sorbian. According to language experts, Upper Sorbian is expected to survive into the 21st century.[citation needed]
