The population reached its peak in 2021 with 1,054 residents. This rapid growth likely altered the neighborhood's character and increased demand for local services.

In 2022, the population decreased to 810 residents, which remains significantly higher than pre-2020 levels. This decline may indicate stabilization after rapid growth or could be due to factors affecting housing or employment in the area.

Population density figures correlate with these changes. The density peaked at 4,413.47 people per square mile in 2021 and settled at 3,391.76 in 2022. These figures suggest Johnson Heights transformed from a low-density area to a more densely populated suburban neighborhood.

The density levels indicate that Johnson Heights likely features a mix of housing types, including single-family homes, townhouses, and possibly low-rise apartments. The neighborhood probably supports a suburban lifestyle with access to community amenities.

The rapid population growth since 2020 may have led to increased development of infrastructure and services to accommodate new residents. This growth might have attracted new businesses and services, potentially enhancing the area's appeal.

In conclusion, Johnson Heights has transitioned from a less populated area to a more densely inhabited suburban neighborhood. These demographic shifts likely reflect broader trends in Sacramento's urban development and may indicate Johnson Heights' growing attractiveness as a residential area within the city.
