Climate

Climate typeClimate typePAGASA sorts the country's climate into four types by when the rain falls. Type I has a dry season from November to April and a wet one for the rest of the year; Type II has no dry season, with the most rain from December to February; Type III has a short dry season; Type IV has rain spread through the year.More in the glossary

Type III[32]

No clear rainiest time of year, and a short dry season of one to three months, in December to February or in March to May.

Covers about 63 of every 100 parts of its land. Read by Scene off PAGASA's climate map, so approximate: the type that covers most of the place's land.

Life & Economy

About 13 of every 100 people lived below the poverty line in 2021.
Poverty, 2021Poverty incidenceHow many of every 100 people live in families whose income is below the poverty line: what a person needs in a year for food and other basic needs, as the PSA sets it for each province. It is an estimate, from a survey or, for a town, a statistical model, so the PSA gives a range it is likely to fall in.More in the glossary
13.2% of people[19]Below the poverty line, by the PSA's estimate for every town.
Income classIncome classThe Department of Finance sorts provinces, cities and municipalities into classes by their average yearly income over recent years: 1st class has the most. It measures the local government's income, not how well off its people are.More in the glossary
1st class[4]
About 13 of every 100 people in Santa Ana lived below the poverty line in 2021 (13.2%)[19]

The PSA's model for every town puts it between 10.0% and 16.4%, with 90% confidence.

The PSA rates this estimate's reliability as acceptable rather than high: read it as a guide.

History & Identity

Created
President Elpidio Quirino signed Executive Order No. 289 on 21 October 1949. It created the municipality of Santa Ana out of the northeastern part of Gonzaga. The order said the new town would begin to exist on 1 January 1950.[9]

How it got its name

Local traditionThe municipal history page says the place was first called Palawig, from a Negrito word, "pasawig", meaning the mouth of a river.[11]

Local traditionThe municipal history page says the name Santa Ana is not a saint's name. It says the letters ANA come from the family names of Governor Arranz and Board Members Navarro and Avena, who held office when the town was born.[11]

Its story

The site of Santa Ana was called Palawig. Its first people were Negritos and woodcutters, according to the town's own history page.[11]

After Gonzaga was created in 1918, fishermen from Minanga settled on the river banks at Palawig.[11]

In 1935 two settler groups joined and began to work to separate Palawig from Gonzaga. Their request was held back because the population was about 3,000 and 5,000 was required.[11]

The war stopped the effort. It resumed in the late 1940s through a Provincial Board member named Navarro.[11]

Executive Order No. 289 of 21 October 1949 separated Palawig and other barrios from Gonzaga from 1 January 1950, and the new town took the name Santa Ana.[11]

A boundary dispute with Gonzaga delayed the inauguration to 6 March 1950. The first town hall stood in Palawig. The municipal government moved to its present site on 1 June 1957.[11]
