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.
answer:
How many people live in the Federal District?

question:
Government revenues largely come from sales of fishing licenses, income from the Tuvalu Trust Fund, and from the lease of its highly fortuitous .tv Internet Top Level Domain (TLD). In 1998, Tuvalu began deriving revenue from the use of its area code for premium-rate telephone numbers and from the commercialisation of its ".tv" Internet domain name, which is now managed by Verisign until 2021. The ".tv" domain name generates around $2.2 million each year from royalties, which is about ten per cent of the government's total revenue. Domain name income paid most of the cost of paving the streets of Funafuti and installing street lighting in mid-2002. Tuvalu also generates income from stamps by the Tuvalu Philatelic Bureau and income from the Tuvalu Ship Registry.
answer:
How much money does Tuvalu's tv domain name earn each year?
