When a Mississippi statute says "latest available federal census," do you use the prior official census or the new one's preliminary numbers?
Plain-English summary
The City of Indianola was about to appoint a new municipal court judge in September 2021. The eligibility rules for municipal judges depend on the city's population: cities with 10,000 or more use Section 21-23-3's stricter rules; smaller cities use Section 21-23-5's more flexible rules. Both statutes refer to the "latest available federal census."
Indianola had a population of over 10,000 in the 2010 census but the 2020 estimates suggested it had dropped below 10,000. Which counted as the "latest available federal census" in September 2021, when the 2020 census was largely complete but not yet finalized?
The AG said use the 2010 numbers. The 2020 census remained "preliminary" until the Census Bureau formally finalized and published it. Until then, the 2010 official numbers were the controlling "latest available federal census."
The AG drew on Kelly v. City of Aberdeen (1996), a Mississippi Supreme Court case interpreting almost identical language ("latest federal census") in the alcoholic beverage statute (Section 67-1-14(2)(a)). The Court in Kelly held the city had to use the official 1980 census, not preliminary 1990 numbers, when deciding whether to hold a local-option election. The Court's reasoning:
- Statutes use census thresholds to provide "a definite benchmark"
- Preliminary numbers are subject to correction and revision
- Allowing preliminary numbers to control would create "intolerable inconvenience and confusion"
- Stability and uniformity require official numbers
Same logic applied to Section 21-23-3. Indianola, in September 2021, used the 2010 official numbers and treated itself as a 10,000+ city for purposes of the municipal judge appointment.
What this means for you
For Mississippi municipal officials at population thresholds
Whenever a Mississippi statute keys a rule to "latest available federal census" or similar phrasing:
- Use the most recent OFFICIAL census numbers
- Do NOT use preliminary estimates, ACS rolling estimates, or counts from interim Census Bureau releases that are not yet final
- The official numbers control until the next census is officially published
For 2026 reference: the 2020 census is now official (was finalized in 2021/2022 depending on the data product). It is the controlling census for Mississippi statutes referring to "latest available federal census" until 2030 numbers become official.
For city attorneys advising on population-threshold statutes
This rule reaches across Mississippi statutes. Statutes that condition local government structure or authority on population include:
- Municipal judge eligibility (Sections 21-23-3, 21-23-5)
- Form of municipal government (various)
- Salary scales for elected officials (Section 25-3-9 for prosecutors, etc.)
- Various procurement and budget thresholds
When advising clients on which threshold applies, use the official census. Document the source. If clients want to act on preliminary numbers, advise against it; the action could be challenged later when official numbers come out differently.
For Mississippi cities near a population threshold
Plan around census timing. If you suspect your city has dropped below or risen above a critical threshold:
- The official census drives statutory consequences
- The transition is automatic when the new census is published
- For decisions made before the transition (judge appointments, budget allocations, election structures), the old census controls
- For decisions made after, the new census controls
If an action straddles the transition (a five-year judicial appointment that begins under the old census and may continue under the new), the rule of "the law in effect when the appointment is made" generally controls.
For Mississippi judicial appointment authorities
If you are appointing a municipal judge:
- Confirm which population tier your city is in based on the latest official census
- Apply the corresponding eligibility rules
- Document the population basis on the minutes
- If the city's population is in flux because of an upcoming census, make the appointment based on the current official census; do not preemptively use preliminary numbers
For prospective municipal judges and prosecuting attorneys
If you are considering an appointment, your eligibility under Section 21-23-3 (cities 10,000+) requires being a qualified elector of the county, while Section 21-23-5 (cities under 10,000) does not require qualified-elector status (it requires Mississippi license to practice law or being a justice court judge). Population determines which rule applies. Confirm the city's status under the latest official census.
For Census Bureau watchers
The "preliminary versus official" distinction is important. The Census Bureau releases data in stages:
- Apportionment counts (used for congressional reapportionment)
- Public Law 94-171 redistricting data
- Detailed demographic data (American Community Survey rolling estimates, decennial detail tables)
- Tribal-area, place, and other geographic detail
For Mississippi statutory purposes, the official decennial census population (the apportionment-style total population number) is generally the controlling figure. ACS rolling estimates are not the "federal census" for Mississippi statutory threshold purposes.
Common questions
Q: Why does it matter whether you use the 2010 or 2020 census?
A: Population thresholds in statutes can flip a city from one regulatory regime to another. In Indianola's case, falling below 10,000 in 2020 would change the municipal judge eligibility rules. Whether the city was "above" or "below" 10,000 in September 2021 depended on which census you used.
Q: When did the 2020 census become "final" for Mississippi statutory purposes?
A: The Census Bureau released the apportionment counts in April 2021 and the redistricting data (P.L. 94-171) in August 2021. Detailed demographic and characteristic data followed in 2022 and 2023. Mississippi statutes that simply reference "federal census" usually mean the basic decennial total population, which became official with the apportionment release in spring 2021. But the AG opinion in September 2021 still treated the 2020 numbers as not yet finalized for Section 21-23-3 purposes, suggesting the AG's view was that final and official meant the comprehensive published total. As of 2026, the 2020 census is fully official across all data products.
Q: What about the American Community Survey (ACS)?
A: ACS is a different program from the decennial census. Statutes that say "federal census" typically mean the decennial census (the once-every-ten-years population count), not the rolling ACS estimates. If a statute specifies "latest census estimate" or includes ACS by name, the rule may be different.
Q: What if a Mississippi statute uses different census language?
A: Read the statute carefully. "Latest federal decennial census" (decennial only). "Federal census" (likely decennial). "Population estimate by the State Demographer" (different source). "Latest available federal census" (decennial, when officially published, per Kelly and Fratesi). Each formulation has its own scope.
Q: What if the city wants to act based on a preliminary 2020 number that everyone knows is going to be final?
A: Do not. The Kelly case explicitly addressed this temptation. Preliminary numbers are subject to correction. Acting on preliminary numbers risks a later challenge if the final numbers come in differently.
Q: Does this rule apply to county-level population thresholds?
A: Yes. Same logic. The Kelly reasoning applies to any Mississippi statute keyed to federal census population.
Q: Could the legislature change this rule?
A: Yes. The legislature could amend any specific statute to use "the most recent census, including preliminary releases" or some similar formulation. Absent that change, the Kelly default rule applies.
Q: How long after a census is released does it become "available" for purposes of statutes?
A: There is some judgment involved. The AG opinion in September 2021 still treated the 2020 census as not yet final, even though apportionment data had been released months earlier. A reasonable rule: when the Census Bureau publishes the relevant total population data product as final, that becomes the "latest available federal census." Cities should act conservatively and consult counsel near transitions.
Q: Can a city challenge its census count?
A: Yes, through the Census Bureau's count-question and count-challenge processes. Those processes are time-limited. A successful challenge could change the official number. Cities should pursue any challenges promptly after a census release.
Q: How does this affect retroactive challenges to past actions?
A: An action taken when an old census was the latest official census remains valid even after a new census is published. The Kelly rule is forward-looking: at any given decision time, use the then-controlling census.
Background and statutory framework
Section 21-23-3 governs municipal judges and prosecuting attorneys in Mississippi cities. The basic structure:
Cities with 10,000 or more population: Section 21-23-3 applies. Municipal judge must be:
- A qualified elector of the county where the municipality sits (with limited exceptions)
- An attorney at law
Cities with less than 10,000: Section 21-23-5 applies. Municipal judge appointment is discretionary (small cities can choose not to have a municipal judge). If they do appoint, the judge must be:
- An attorney licensed in Mississippi, OR
- A justice court judge of the county
There is also a special rule for cities over 10,000 located in a county over 935 square miles with a county court; those cities can opt to follow Section 21-23-5's rules.
The key population threshold (10,000) is determined by "the latest available federal census."
The Kelly v. City of Aberdeen (1996) precedent gave the Mississippi Supreme Court's authoritative reading of similar language. Kelly involved Section 67-1-14(2)(a), which governs whether municipalities can hold local-option elections to legalize alcoholic beverage sales. The statute keyed to "the latest federal census" with a 7,000 threshold. Aberdeen had 7,064 in 1980 (above threshold) but preliminary 1990 figures suggested it might be below. Aberdeen relied on the 1980 numbers and held the election. The Court approved that approach:
- "The legislature obviously included the words 'according to the latest federal census' in order to avoid confusion and provide a definite benchmark"
- "As long as the census is subject to possible correction for miscounts...there is the danger that a city would have to later declare the local option election invalid"
- "Future election results based on preliminary numbers would merely be a source of intolerable inconvenience and confusion"
- "To promote stability, uniformity, and the avoidance of confusion and duplicate efforts, municipalities must rely on the official results of the latest federal census"
The Fratesi opinion applies the same reasoning to Section 21-23-3. The principle: official numbers, not preliminary estimates.
For Mississippi cities and counties tracking population transitions, the operational rule is:
1. Use the current official decennial census for any statutory population threshold.
2. Wait for the new census to be officially finalized before treating it as controlling.
3. Document the census source on official records when making threshold-dependent decisions.

The Honorable Gary Fratesi
Alderman, City of Indianola
Post Office Box 269
Indianola, Mississippi 38751
Re: Meaning of "Latest Available Federal Census" as Used in Section 21-23-3
Dear Mr. Fratesi:
The Office of the Attorney General has received your request for an official opinion.
Background
The City of Indianola (the "City") is in the process of appointing a new municipal court judge. According to your request, the official 2010 census showed the City having a population over 10,000, but the 2020 census estimates set that number at less than 10,000. The residency requirements for a municipal court judge under Mississippi Code Annotated Sections 21-23-3 and 21-23-5 vary based on population according to the "latest available federal census."
Question Presented
Do the 2010 official census results or the 2020 census estimates constitute the "latest available federal census" as contemplated by Section 21-23-3?
Brief Response
Until the preliminary figures of the 2020 census become finalized and official, the official results from the 2010 census constitute the "latest available federal census" as contemplated by Section 21-23-3.
Applicable Law and Discussion
Section 21-23-3 provides, in relevant part:
In all municipalities having a population of ten thousand (10,000) or more, according to the latest available federal census, there shall be a municipal judge and a prosecuting attorney, who shall be appointed by the governing authorities of the municipality at the time provided for the appointment of other officers. … Except as otherwise provided in Section 21-23-5, a municipal judge shall be a qualified elector of the county in which the municipality is located and shall be an attorney at law.
…
Provided, however the governing authorities of any municipality having a population in excess of ten thousand (10,000) persons according to the latest available federal census and situated in a county having an area in excess of nine hundred thirty-five (935) square miles and having a county court may, in their discretion, follow the provisions as set out in Section 21-23-5 for municipalities having a population of less than ten thousand (10,000).
Miss. Code Ann. § 21-23-3 (emphasis added).
Section 21-23-5 provides:
In any municipality having a population of less than ten thousand (10,000) according to the latest available federal census, it shall be discretionary with the governing authorities of the municipality as to whether or not a municipal judge or a prosecuting attorney, or both, shall be appointed. If the authorities of any municipality having a population of less than twenty thousand (20,000) according to the latest available federal census appoint a municipal judge, he shall be an attorney licensed in the State of Mississippi or a justice court judge of the county in which the municipality is located. The mayor or mayor pro tempore shall not serve as a municipal judge.
Miss. Code Ann. § 21-23-5.
In a case of first impression, the Mississippi Supreme Court was faced with a question regarding similar language, "according to the latest federal census," as it pertained to Section 67-1-14(2)(a), which, at that time, provided that a municipality with a population of "not less than seven thousand (7,000), according to the latest federal census" conduct an election related to whether such municipality could legalize the use, possession, and sale of alcohol within its corporate boundaries. Kelly v. City of Aberdeen, 680 So. 2d 208, 208–9 (Miss. 1996). The City of Aberdeen held such an election. The population the city used to justify holding the special election came from the official census figures of 1980 rather than the preliminary figures for the 1990 census.
The supreme court ruled that the 1980 figures were in fact the controlling figures by reason that:
[t]he legislature obviously included the words "according to the latest federal census" in order to avoid confusion and provide a definite benchmark for determining whether a municipality located in a dry county could legally conduct a local option election. As long as the census is subject to possible correction for miscounts, which would have been the case had Aberdeen relied on [the preliminary figures], then there is the danger that a city would have to later declare the local option election invalid. Future election results based on preliminary numbers would merely be a source of intolerable inconvenience and confusion. To promote stability, uniformity, and the avoidance of confusion and duplicate efforts, municipalities must rely on the official results of the latest federal census . . . .
Kelly, 680 So. 2d at 209–10.
Consistent with the court's reasoning and ruling in Kelly, it is our opinion that the official figures from the 2010 census constitute those of the "latest available federal census," as contemplated by Section 21-3-3 and will remain such until the 2020 figures are finalized and made official by the Federal Census Bureau.
