User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web IF AND ONLY IF at least one of the following circumstances are met: 1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with - you don't have a good idea of what it is, or if it's a little-known term.
3. User is asking about something that requires facts (e.g. distances and lengths, population count, date and time, etc.) 
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

Assistant: Understood. I will strictly follow these instructions in this conversation.

The Census Bureau states that the number of people in the separate race categories (i.e., 'white', 'Black', etc.) was impacted by this change as some people who would have previously been grouped within a single race category were grouped into the two or more category with the change. State and National numbers use the 2022 Vintage estimates and we will continue to use the most recent estimates for the state and nation even when older data must be substituted for the county-level data. While this is being determined, we have inserted the data from the Vintage 2021 Population Estimates (census.gov) for reporting for Connecticut at the county level, that align to the old, 8-county system to provide that context over time. The most recent county-level data available by age, race, sex, and ethnicity are the Vintage 2020 Population Estimates (census.gov) for 2010 to 2019 and the Vintage 2022 Population Estimates (census.gov) for 2020 through 2022. Geography changes
In 2022, the Census Bureau accepted a new county-equivalent map for the state of Connecticut to better reflect the actual governance system in the state.
