The continuing campaigns to eradicate illiteracy also were a part of basic education. Chinese government statistics indicated that of a total population of nearly 1.1 billion in 1985, about 230 million people were illiterate or semiliterate. The difficulty of mastering written Chinese makes raising the literacy rate particularly difficult. In general, language reform was intended to make writing and the standard language easier to learn, which in turn would foster both literacy and linguistic unity and serve as a foundation for a simpler written language. In 1951 the party issued a directive that inaugurated a three-part plan for language reform. The plan sought to establish universal comprehension of a standardized common language, simplify written characters, and introduce, where possible, romanized forms based on the Latin alphabet. In 1956 Putonghua (Modern Standard Chinese) was introduced as the language of instruction in schools and in the national broadcast media, and by 1977 it was in use throughout China, particularly in the government and party, and in education. Although in 1987 the government continued to endorse the goal of universalizing Putonghua, hundreds of regional and local dialects continued to be spoken, complicating interregional communication.
