Question: Up to the 1990s, the Federal District was the most populous federal entity in Mexico, but since then its population has remained stable at around 8.7 million. The growth of the city has extended beyond the limits of the Federal District to 59 municipalities of the state of Mexico and 1 in the state of Hidalgo. With a population of approximately 19.8 million inhabitants (2008), it is one of the most populous conurbations in the world. Nonetheless, the annual rate of growth of the Metropolitan Area of Mexico City is much lower than that of other large urban agglomerations in Mexico, a phenomenon most likely attributable to the environmental policy of decentralization. The net migration rate of the Federal District from 1995 to 2000 was negative.
Is there an answer to this question: What was the migration rate of Mexico City from 95-2000?

Answer: negative


Question: Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. Developed in conjunction with the Universal Coded Character Set (UCS) standard and published as The Unicode Standard, the latest version of Unicode contains a repertoire of more than 120,000 characters covering 129 modern and historic scripts, as well as multiple symbol sets. The standard consists of a set of code charts for visual reference, an encoding method and set of standard character encodings, a set of reference data files, and a number of related items, such as character properties, rules for normalization, decomposition, collation, rendering, and bidirectional display order (for the correct display of text containing both right-to-left scripts, such as Arabic and Hebrew, and left-to-right scripts). As of June 2015[update], the most recent version is Unicode 8.0. The standard is maintained by the Unicode Consortium.
Is there an answer to this question: Who maintains the Unicode Standard?

Question: The Republic of Liberia, beginning as a settlement of the American Colonization Society (ACS), declared its independence on July 26, 1847. The United States did not recognize Liberia's independence until during the American Civil War on February 5, 1862. Between January 7, 1822 and the American Civil War, more than 15,000 freed and free-born Black Americans from United States and 3,198 Afro-Caribbeans relocated to the settlement. The Black American settlers carried their culture with them to Liberia. The Liberian constitution and flag were modeled after the United States.

Is there an answer to this question: When did the American Civil War end?

Answer: unanswerable
