The US Counties Population API provides detailed population statistics for US counties, including current population data for the year 2024 and previous population data for the year 2020.
The API delivers data in standard JSON format, ensuring compatibility with various applications and systems.
To access population data for a specific county, you can make a request to the API endpoint with the county name and state as parameters, and it will return the relevant population statistics.
Yes, the API provides population data for both the current year (2024) and the previous year (2020), allowing users to perform historical population analysis.
Each endpoint returns specific population-related data. The "us states list" endpoint returns a list of US states. The "get counties by state" endpoint returns counties for a specified state. The "get current population by county" endpoint provides the current population for a specified county, while the "get previous population by county" endpoint returns the population from 2020 for that county.
Key fields in the response data include "state" and "counties" for the counties endpoint, "county," "state," and "current_population" for the current population endpoint, and "county," "state," and "previous_population" for the previous population endpoint. These fields provide essential information for identifying and analyzing population statistics.
The response data is organized in JSON format, with each endpoint returning a structured object. For example, the current population endpoint returns an object containing the county name, state, and current population value, making it easy to parse and utilize in applications.
The "get counties by state," "get current population by county," and "get previous population by county" endpoints require specific parameters. Users must provide the state name for the counties endpoint and the county name for the population endpoints to retrieve the relevant data.
The "us states list" endpoint provides a comprehensive list of US states. The "get counties by state" endpoint offers a list of counties within a specified state. The population endpoints provide current and previous population figures for specified counties, allowing users to analyze demographic changes over time.
Users can customize their data requests by specifying the desired state or county in the API call. For example, to get counties in California, users would call the "get counties by state" endpoint with "California" as a parameter. Similarly, they can specify a county to retrieve its current or previous population.
Typical use cases include demographic analysis, urban planning, resource allocation, and academic research. Users can leverage the data to understand population trends, compare county populations, and assess changes over time, which is valuable for policymakers and researchers.
Data accuracy is maintained through regular updates and validation against reliable sources, such as census data and government reports. The API aims to provide accurate and up-to-date population statistics, ensuring users can trust the information for analysis and decision-making.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs.
