In 2006, crime in Santa Monica affected 4.41% of the population, slightly lower than the national average crime rate that year of 4.48%. The majority of this was property crime, which affected 3.74% of Santa Monica's population in 2006; this was higher than the rates for Los Angeles County (2.76%) and California (3.17%), but lower than the national average (3.91%). These per-capita crime rates are computed based on Santa Monica's full-time population of about 85,000. However, the Santa Monica Police Department has suggested the actual per-capita crime rate is much lower, as tourists, workers, and beachgoers can increase the city's daytime population to between 250,000 and 450,000 people.

The Santa Monica Police Department suggests that the per-capita crime rate sways in what way?
much lower
