Report P-3: Population Projections Race/Ethnicity and Sex by Individual Years of Age, 2010 to 2060
California (2019 Baseline)

Data Notes:
"The California Department of Finance (DOF), Demographic Research Unit is responsible by statute for maintaining postcensal population projections which are calculated using the demographic balancing equation:

Current Population = Previous Population + (Births - Deaths) +Net Migration

This method calculates the population in the target year by starting with the population from the previous year, adding natural increase (births minus deaths) and net migration that occurred during the time period between the two years. The births, deaths, and migration anticipated during the time period are called the components of change. A cohort-component method traces people born in a given year throughout their lives. As each year passes, cohorts change due to the mortality and migration assumptions. Applying fertility assumptions to women of childbearing age forms new cohorts at age zero.

These 2019 baseline projections incorporate the latest historical population, birth, death, and migration data available as of July 1, 2020. Historical trends from 1990 through 2020 for births, deaths, and migration are examined. County populations by age, sex, and race/ethnicity are projected to 2060. The county projections are then summed to obtain data for the state. "

Data: Test Results for California's Assessments

English Language Arts Definition: Percentage of public school students in grades 3, 4, 5, 6, 7, 8, and 11 scoring in the standard met or standard exceeded achievement level on the CAASPP Smarter Balanced Summative Assessment for English language arts/literacy (ELA), by grade level (e.g., in 2021, 59.2% of 11th graders in California met or exceeded their grade-level standard in ELA).

Mathematics Definition: Percentage of public school students in grades 3, 4, 5, 6, 7, 8, and 11 scoring in the standard met or standard exceeded achievement level on the CAASPP Smarter Balanced Summative Assessment for mathematics, by grade level (e.g., in 2021, 34.4% of 11th graders in California met or exceeded their grade-level standard in mathematics).

Footnote: Years presented are the final year of a school year (e.g., 2020-21 is shown as 2021). Visit the California Assessment of Student Performance and Progress (CAASPP) website for detailed information about the CAASPP system and explanations of the achievement levels. Assessments were not administered in 2020. Due to changes in administration, and low and uneven participation in 2021, the Dept. of Education (2020-21 CAASPP and ELPAC Assessment Results) advises against comparing data for 2021—annotated here with an asterisk (*)—with earlier years. The notation S refers to data that have been suppressed because there were fewer than 20 students in that group. N/A means that data are not available.
