Antonio based on the fact the city had 336 residential water customers at the time. The Clerk further asserted that most of the residents received their mail via post office box, which the US Census Bureau would not send forms to. City officials speculated that the population that year was probably closer to 900, which would be more consistent with the growth reflected in data collected in other cities throughout the county, as well as Pasco County as a whole. The 2010 census count of 1,138 residents was considered to be much more accurate. Education San Antonio is home to two schools. Saint Anthony Catholic School (grades K–8) traces its roots to the Fall of 1883 when local widow Cecilia Morse began teaching colony children in her home. By April 1884 it was officially established as a Catholic school and is by far the oldest school of any kind in Pasco County. In fact it actually predates the county by several years. San Antonio Elementary (grades K–5) was founded 98 years later in 1981 and though its campus lies entirely within San Antonio's city limits, its mailing address is actually Dade City, Florida. Holy Name Academy (grades 1–12) was established in 1889 as an "all-girls" boarding school by the Benedictine Sisters of Florida, but moved to the neighboring town of St. Leo in 1911.
