Chiyoda consists of the Imperial Palace and a surrounding radius of about a kilometer. As of June 2020, the ward has an estimated population of 66,575, and a population density of 5,709 people per km², making it by far the least populated of the special wards. The total area is 11.66 km², of which the Imperial Palace, Hibiya Park, National Museum of Modern Art, and Yasukuni Shrine take up approximately 2.6 km², or 22% of the total area.
Chiyoda is an economical powerhouse, the small area East of the palace in the districts of Otemachi, Marunouchi and Yurakucho (colloquially "Daimaruyu") houses the headquarters of 19 Fortune 500 companies, is the source of roughly 10% of the combined revenue of all Japanese companies and produced in 2017 the equivalent of around 1/4th of the GDP of the country. With a day population of around 850,000, its day/night population ratio is by very far the highest of all municipalities in Japan.
At the tip of Musashino plateau, Chiyoda is located at the very heart of former Tokyo City in eastern mainland Tokyo. The central area of the ward is furthermore occupied by the Imperial Palace. The east side of the ward, bordering Chūō, is the location of Tokyo Station. The south side, bordering Minato, encompasses Hibiya Park and the National Diet Building. It is almost exclusively occupied by administrations and agencies. The west and northwest are primarily upper class residential; the Yasukuni Shrine is also there. The "high lantern" of Kudanzaka slope was not originally built as a lighthouse, but was built as a lantern for the Shrine. Originally steep and with steps, the slope was considerably softened during remediation after the Kanto earthquake. To the north and northeast of the ward are several residential neighborhoods and the Akihabara commercial district.

Chiyoda is run by a directly elected mayor and a city assembly of 25 elected members. The current mayor is Takaaki Higuchi.
For the Metropolitan Assembly, Chiyoda forms a single-member electoral district. It had been represented by Liberal Democrats for 50 years until the landslide 2009 election when then 26-year-old Democratic newcomer Zenkō Kurishita unseated 70-year-old former Metropolitan Assembly president and six term assemblyman, Liberal Democrat Shigeru Uchida. In the 2013 election, no Democrat contested the seat and Uchida won back the district against a Communist and two independents.

On December 31, 2001, Chiyoda had 6,572 buildings which were four stories or taller.
Some of the districts in Chiyoda are actually not inhabited, either because they are parks (Hibiya Koen), because they consist only of office buildings (Otemachi or Marunouchi), and/or because they are extremely small. The area on the eastern side of Akihabara Station is the location of several districts that cover at most a few buildings. Kanda-Hanaokachō is, for example, limited to the Akihabara Station and the Yodobashi Camera department store. Understanding the address system in the Kanda area can be particularly troublesome for non-locals.
