Population Dashboards

The databases, information, and other data have been taken from the American Community Survey 1-Year from the official website of The United States Census Bureau (https://data.census.gov/).

The American Community Survey is conducted every year through sampling and provides estimates on a variety of demographic variables. Not every county is included in the 1-year survey due to their low populations.

On this page, we were able to obtain data related to the population of the United States, from the national level to the county level. We found a database that gathered information about every county in the state of California, updated annually.

There were a number of attributes that we did not need and that were not necessary, so we focused on the following variables:

As you can see, we have many attributes and the groups are not really interesting, so we decided to regroup the ages to form the following age groups:

Once the data is cleaned, we end up with a single dataset with all the information for each county. That is to say, the final dataset consists of the variables mentioned above, apart from the variables 'County' and 'Year'.

Total Population of Califronia

Until 2018, California's population demonstrated a consistent increase. However, from that point onwards, a gradual decline in demographic growth was observed, leading to a downward trend in the subsequent years until 2022. This shift marked a turning point in the state's population dynamics, signaling a change in the direction of demographic growth that had been steady until 2018.

This decline in population in California can be attributed to several factors:

Over 100,000 deaths due to COVID-19
Declining birthrate near record lows
People moving out of state for a lower cost of living, often while working remotely for technology companies based in California
Sharp drop in immigration due to the pandemic and federal policies
