Possible Undercounts Could Be Costly for Some Local Cities

TIMES STAFF WRITER

The populations of Camarillo and Thousand Oaks may have been substantially undercounted by the new U.S. Census 2000, a glitch that could cost big money if left uncorrected, city officials said Friday.

Meanwhile, Oxnard officials said they are pleased with the new census, because it counted 10,000 more residents than anticipated in a pre-census estimate.

In all, census population totals released Thursday were lower than state Department of Finance pre-census estimates in six local cities and higher in four.

“It’s possible some cities didn’t participate in the census’ address-checking program,” said planner Steve Wood, chief census analyst for Ventura County. “So new neighborhoods could have been missed.”

A study by the U.S. Conference of Mayors has calculated that each person missed in the census costs local government $129 to $175 a year. Census officials estimate the potential benefit of each extra person at $150 to $190 a year.

Either way, Oxnard’s extra 10,000 residents could mean millions more dollars from Sacramento and Washington each year--a payoff for an aggressive census outreach program that sent multilingual workers to parks, churches, athletic fields and supermarkets to help residents complete their census forms.

“[The] outreach program demonstrates how an effective grass-roots effort can pay off for local taxpayers,” said Oxnard Mayor Manuel Lopez.

The flip side of that may be the Camarillo census count. City officials say they did everything right, even getting census counters to add 2,000 missed addresses to their list of Camarillo dwellings.

Still, the census reported Thursday that Camarillo’s population increased just 9.1% during the 1990s, far short of the state Department of Finance’s pre-census estimate of 21%. That amounts to an undercount of perhaps 6,000 residents, officials said. The census counted 57,077 residents and the city thinks the count should be about 63,000.

“We’re perplexed and puzzled,” said Larry Davis, assistant city manager. “But until we get more details so we can start comparing census track by census track, there’s not much we can do. But we’ll track down the discrepancy.”

Davis said he could not understand how the city could build so many new dwellings over the last decade--about 3,500--and be credited with only 4,774 more residents. Camarillo historically has averaged nearly three people per dwelling. So the new construction would accommodate 10,000 more residents.

Equally puzzling, Davis said, is how the census found that Camarillo lost white population even as new subdivisions were being built in upscale Mission Oaks, Sterling Hills and Spanish Hills.

“How we didn’t grow in the non-Hispanic sector is beyond me,” Davis said.

If errors can be proved, census officials have pledged to revise the figures.

In Thousand Oaks, the potential undercount was about 3,800 people. The census found about 117,000 residents, not the nearly 121,000 that state analysts had projected from a host of variables.

“It’s possible that we may have had 3,000 people undercounted,” said Deputy City Manager Scott Mitnick. “We’ve always felt more comfortable with the state Department of Finance numbers anyway.”

Planning Manager Paul Metrovitsch said Thousand Oaks doesn’t really know yet where the problem lies.

“But we’re going to be studying it,” he said. “We’ll figure out the discrepancy.”

Cities with census counts in excess of state pre-census estimates were Oxnard, +10,053; Moorpark, +1,688; Santa Paula, +1,343; Fillmore, +383.

Cities with census counts lower than state pre-census estimates were: Camarillo, -6,258; Thousand Oaks, -3,793; Ventura, -2,589; Simi Valley, -1,672; Port Hueneme, -1,633; Ojai, -396.

For the county overall, the census found 3,304 fewer residents than the state estimate.
