Honolulu is the capital and largest city of the U.S. state of Hawaiʻi. It is an unincorporated part of and the county seat of the City and County of Honolulu along the southeast coast of the island of Oʻahu. The city is the main gateway to Hawaiʻi and a major portal into the United States. The city is also a major hub for international business, military defense, as well as famously being host to a diverse variety of east-west and Pacific culture, cuisine, and traditions.

Honolulu is the most remote city of its size in the world and is the westernmost major U.S. city. For statistical purposes, the United States Census Bureau recognizes the approximate area commonly referred to as "City of Honolulu" (not to be confused with the "City and County") as a census county division (CCD). Honolulu is a major financial center of the islands and of the Pacific Ocean. The population of the Honolulu census designated place(CDP) was 359,870 as of the 2017 population estimate, while the Honolulu CCD was 390,738 and the population of the consolidated city and county was 953,207.

Honolulu means "sheltered harbor" or "calm port". The old name is Kou, a district roughly encompassing the area from Nuʻuanu Avenue to Alakea Street and from Hotel Street to Queen Street which is the heart of the present downtown district. The city has been the capital of the Hawaiian Islands since 1845 and gained historical recognition following the attack on Pearl Harbor by Japan near the city on December 7, 1941.

As of 2015, Honolulu was ranked high on world livability rankings, and was also ranked as the 2nd safest city in the U.S. It is also the most populated Oceanian city outside Australasia and ranks second to Auckland as the most-populous city in Polynesia.

Hilo is the largest settlement and census-designated place (CDP) in Hawaii County, Hawaii, United States, which encompasses the Island of Hawaiʻi. The population was 43,263 at the 2010 census.

Hilo is the county seat of the County of Hawaiʻi and is in the District of South Hilo. The town overlooks Hilo Bay, at the base of two shield volcanoes, Mauna Loa, an active volcano, and Mauna Kea, a dormant volcano and the site of some of the world's most important ground-based astronomical observatories. Much of the city is at some risk from lava flows from Mauna Loa. The majority of human settlement in Hilo stretches from Hilo Bay to Waiākea-Uka, on the flanks of Mauna Loa.

Hilo is home to the University of Hawaiʻi at Hilo, ʻImiloa Astronomy Center of Hawaiʻi, as well as the Merrie Monarch Festival, a week-long celebration of ancient and modern hula that takes place annually after Easter. Hilo is also home to the Mauna Loa Macadamia Nut Corporation, one of the world's leading producers of macadamia nuts. The town is served by Hilo International Airport.

Vancouver  is a coastal seaport city in western Canada, located in the Lower Mainland region of British Columbia. As the most populous city in the province, the 2016 census recorded 631,486 people in the city, up from 603,502 in 2011. The Greater Vancouver area had a population of 2,463,431 in 2016, making it the third-largest metropolitan area in Canada. Vancouver has the highest population density in Canada with over 5,400 people per square kilometre, which makes it the fifth-most densely populated city with over 250,000 residents in North America behind New York City, Guadalajara, San Francisco, and Mexico City according to the 2011 census. Vancouver is one of the most ethnically and linguistically diverse cities in Canada according to that census; 52% of its residents have a first language other than English.[8][9] Roughly 30% of the city's inhabitants are of Chineseheritage. Vancouver is classed as a Beta global city.

Vancouver is consistently named as one of the top five worldwide cities for livability and quality of life, and the Economist Intelligence Unit acknowledged it as the first city ranked among the top-ten of the world's most well-living cities for five consecutive years. Vancouver has hosted many international conferences and events, including the 1954 British Empire and Commonwealth Games, UN Habitat I, Expo 86, the World Police and Fire Games in 1989 and 2009; and the 2010 Winter Olympics and Paralympics which were held in Vancouver and Whistler, a resort community 125 km (78 mi) north of the city. In 2014, following thirty years in California, the TED conference made Vancouver its indefinite home. Several matches of the 2015 FIFA Women's World Cup were played in Vancouver, including the final at BC Place.
