3. Orange County

Note

Self-Response Rates (SRR) DO NOT indicate the overall share of households or people counted in the census, but rather the share of housing units that filled out the form on their own.

City statistics such as population, race/ethnic demographic breakdown, and “hard-to-count” (HTC) characteristics are based on 2015-2019 ACS 5-year estimates and not the results of the 2020 Census.

See the Methodology section for information about how these numbers are calculated.

Orange County Summary


Orange County’s final 2020 self-response rate (SRR) was 76.6%, which was higher than its SRR in the 2010 census (71.7%) The lowest self-responding tracts in the county had a SRR in the 0-15% range while the highest self-responding tracts had a SRR in the 85-100% range.

116 tracts were among the bottom 20% lowest self-responding tracts in Orange County (below 71% SRR). Of those tracts, the largest share of the population was Hispanic/Latino of Any Race (54.3%) (mostly “Mexican” at 49.1%), followed by White (non-Hispanic) (29.1%). The most prominent hard-to-count (HTC) characteristics were households that were rented (65.8%), multi-unit structures (52.3%), and households that were non-family (35.4%).

Of the top 20% highest self-responding tracts in Orange County, the largest share of the population was White (non-Hispanic) (58.5%), followed by Asian (non-Hispanic) (19.6%) (mostly “Chinese” and “Vietnamese” at 4.6% and 4.1% respectively). The most prominent HTC characteristics were people born outside of the U.S. (20.9%) and households that were non-family (19.0%).

When looking at the Top and Bottom 20% Analysis, it is also important to note if any race/ethnic groups and HTC characteristics are under or overrepresented compared to their estimated share of the county’s population. For instance, the estimated White (non-Hispanic) population in Orange County is 40.6% but White (non-Hispanic) makes up 58.5% of the top 20% highest self-responding tracts in Orange County. On the other hand, the estimated Hispanic/Latino of Any Race population in Orange County is 34.1% but Hispanic/Latino of Any Race makes up 54.3% of the bottom 20% lowest self-responding tracts in the county.

The data and analysis in the Orange County Census Atlas is enriched by local knowledge and narratives about community efforts that may have contributed to a city or group’s increased self-response rate.

According to reports shared by Charitable Ventures Orange County, outreach partners funded by OC Counts conducted education, outreach, and questionnaire assistance activities that garnered the greatest number of impressions in Garden Grove, Orange, Anaheim, Santa Ana and Irvine. The top 5 activity types that created the most impressions were social media, advertising, “other,” “media_other” and phone banking. Other notable activities that garnered a significant amount of impressions were an in-language commercial aired on Khmer TV, street banners, full page ads on Korea Daily and Korea Times, and a Census Caravan in Santa Ana.

Reports collected from OC Counts’ funded partners also revealed that outreach activities that garnered the most impressions specifically from HTC groups were conducted in Orange, Santa Ana, Irvine, Garden Grove and Anaheim. Among HTC groups, social media, phonebanking, “other,” events, and collateral were the top 5 activity types that created the most impressions. Other notable activities that garnered a significant amount of impressions among HTC groups were the in-language commercial aired on Khmer TV; one-on-one conversations with friends, family and registered voters; scripts about the census on a toll free phone line; reminding drivers to fill out the census at drive-thru food drive; and census reminders incorporated into wellness or check-in calls during the COVID-19 pandemic.

Race/Ethnic Demographic Breakdown


The following table shows the race/ethnic demographic distribution and final 2020 self-response rates (SRR) in the county. The listed SRR for race/ethnic groups refers to the calculated SRR for all census tracts where the group’s estimated share of the population is greater than or equal to the estimated share of the population for the county. It does not demonstrate the SRR of the whole group.

CORRECT INTERPRETATION: The calculated self-response rate in Orange County census tracts where the estimated Asian (non-Hispanic) population made up at least 20.3% of the population was 77.1%.

INCORRECT INTERPRETATION: The Asian (non-Hispanic) population had a self-response rate of 77.1% in Orange County.

“Hard-to-Count” (HTC) Characteristic Breakdown


The following table shows the “hard-to-count” (HTC) characteristics and final 2020 self-response rates (SRR) in the county. The SRR for a HTC characteristic refers to the calculated SRR in those census tracts where the characteristic’s estimated percentage is greater than or equal to the estimated percentage for the county. It does not demonstrate the SRR for specific types of households (i.e. that are rented) or populations (i.e. that are children under 5).

CORRECT INTERPRETATION: The calculated self-response rate for census tracts in Orange County where at least 42.6% of all occupied housing units were rented was 71.7%.

INCORRECT INTERPRETATION: Rented households had a self-response rate of 71.7% in Orange County.

SRR Analysis - Race/Ethnic Group


The following graphs show the progression of self-response rates (SRR) over time in the county, disaggregated by race/ethnic group. Each data point represents the calculated SRR for all census tracts where the group’s share of the population is greater than or equal to their share of the population for the county. It does not demonstrate the SRR of the whole group.

SRR Analysis - HTC Characteristic

The following graphs show the progression of self-response rates (SRR) over time in the county, disaggregated by select “hard-to-count” (HTC) characteristics. Each data point represents the calculated SRR in those census tracts where the characteristic’s estimated percentage is greater than or equal to the estimated percentage for the county. It does not demonstrate the SRR for specific types of households (i.e. that are rented) or populations (i.e. that are children under 5).
