Located at the heart of Metro Manila, Mandaluyong is bounded on the north by the City of San Juan, on the northeast by Quezon City, on the east by Pasig City, on the south by Pasig River and Makati City, and on the west by San Juan and Pasig Rivers and the City of Manila (Map 1.0.).
Specifically, Mandaluyong lies between Latitudes 14Ë34’00” and 14Ë36’00”, and Longitudes 121Ë01’00” and 121Ë03’00”.
Mandaluyong is the 6th smallest city in the Philippines with a total land area of 1,126 hectares (11.26 km2).
This constitutes 1.77 % of the 636 sq. km. total land area of Metro Manila which is composed of 16 cities and 1 municipality.
The city is composed of 27 barangays, divided into two (2) political districts.
The four (4) largest barangays are Wack-Wack which comprises one-fourth (288.50 has.) of the city’s total land area, followed by Brgy. Addition Hills at about 10.70% (120.36 has.), third and fourth in the list are Brgys. Highway Hills and Plainview at about ten percent each, or 116.12 and 108.88 has., respectively (Table 4.01).
Mandaluyong is underlain with water tables which are still good sources of underground water for domestic uses. Water pumps and deep wells are still being used in many parts of the city to augment water supply from the Manila Water Company.
The cityâs terrain is partially flat on its southwest portion and mostly rolling with gentle slopes in the rest of the area.
CLIMATOLOGICAL CHARACTERISTICS
Mandaluyong City experiences the same climatic conditions prevailing over the whole of Metro Manila, which are being monitored by Station 430 of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) located at Science Garden in Quezon City.
An earthquake can be an imperceptible ground shaking to a violent movement caused by the sudden displacement of rock materials below the surface of the earth. Typhoons during the wet season greatly affect the city and the rest of Metro Manila. Heavy rains, even of short duration, results to flooding in some areas of Mandaluyong.
Once abundant with trees that provided wood for furniture-making, the natural vegetation in the city has been reduced to rows of full-grown acacia trees lining the shoulders of Acacia Lane and spare stands of trees in private lots, subdivisions and school compounds. There are no record of fauna species in Mandaluyong except for domesticated animals such as dogs and cats and other household pets like rabbits, white mice and love birds. Common birds and insects could also be found in the periphery such as maya, a variety of butterflies and other garden insects.

The 2015 Census gave a new population count of 386,276, around 3% of the 12,877,253 population for NCR in the same year. Among the 17 cities and municipalities in the region, Mandaluyong ranked as the 5th smallest in population.
Following the 3.12% growth rate of the city, estimated population for 2020 is 450,414 with a total 112,604 households.
In the absence of published information and studies concerning daytime population in the city, there is a suggestion that having acquired a full level of urbanization, Mandaluyong City follows the trend in Makati City by which daytime population is three (3) to four (4) times its night time population.
LIBERATION DAY
February 9, 1945 – During World War II, Mandaluyong lost many of her people, among them were Catholic priests and civilians. Destruction was felt all over, but with the timely arrival of the American Liberation Forces on February 9, 1945, the municipality was saved from further damages. That day became a red calendar day for Mandaluyong marking its liberation from the Japanese Imperial forces by the Americans.
CITYHOOD
February 9, 1994 – By virtue of Republic Act No. 7675 otherwise known as "An Act Converting the Municipality of Mandaluyong into a Highly Urbanized City to be known as the City of Mandaluyong" was signed by President Fidel V. Ramos on 9 February 1994, which was ratified through a plebiscite on 10 April 1994 making Mandaluyong the 5th city in Metro Manila.
