Population over time

2 figures

Port Mansfield grew from 226 to 319 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

WhenEvent Place namedHarm What the report says
July 2020Flash FloodPort Mansfield$5,980,000Reports of high flowing water blocking passage along SR-186 just west of Port Mansfield were received during the evening of July 25th, when feeder bands into the eastern semicircle of then-Tropical Storm Hanna dropped an additional 4 to 8 inches of rainfall into central and eastern Willacy County. Other flooding was noted in poor drainage locations of Raymondville, and there was an unknown amount of field flooding in eastern Willacy County due to an estimated 11 to 13 inches of rainfall through the duration of the event, which began during the mid afternoon of July 25th. ||Water depths of 2 to 3 feet were likely in some areas, though specifics were unknown. A known poor drainage location at an apartment complex in south Raymondville had up to 3 feet of water depth in parking areas, blocking access to the facility. Other flood related damage in central Willacy County was minimal. In Port Mansfield, where nearly 15 inches of rain fell, including 9 inches in initial inner eyewall bands on July 25th, sandy soil and antecedent dry conditions kept flooding to a minimum. ||Crop damage from flooding rain was significant in Willacy County, including a heavy loss of cotton lint (or bolls) which were destroyed by the flood. Estimates suggest that $36 million in cotton crop was lost from Hanna's flooding rains.||Property damage from flood waters was calculated using NCEI's total dollar damage estimate (divided among the affected counties by local storm data experts). Total property damage from flood waters for Willacy County was $5.98 million.
