• State Demographer, Office of State Budget and Management• State, County, Municipalities, Subcounty Areas• Previous year certified, standard and revised estimates• Estimates used by other agencies for planning/statistical reporting• Estimates used by DOR, DOT and other agencies to distribute state
funds• Census Bureau
• State, County, Incorporated Places, Subcounty Areas• Previous year and revised annual estimates• Estimates used to weight Census Bureau Surveys (i.e. ACS)• Estimates used by agencies for planning/statistical reporting• Estimates used to distribute various federal funds
Population Estimates Require Accurate 2020 Census Count!

North Carolina Demographic Information Survey (NCDiS)
• http://ncds.osbm.nc.gov/
• Data collected from end of June through 3rd week in July
• Annexation Survey (Municipalities Only)• New Annexations Since January 2010 through July 1 of Current Year• New Building Activity on Previously Reported Annexations• IMPORTANT FOR CERTIFIED ESTIMATES
• New Construction & Mobile Home Survey• Supplement to Census Bureau Building Permit Survey
• Group Quarters Survey• Verify Location, Name, Operations of Existing Facility• Indicate New or Missing Facilities• Provide Population Counts for Some Facilities

How to Review Population Estimates
• Missing Annexation
• Certified and Standard population estimates should not match IF you have had annexations within the last year that included occupied housing
• Significant Deviation from Past Trends
• Decline/growth after growth/decline
• Rapid change after slow/no change
• Difference Between Population Trend and Other Indicators
• Building permit growth vs. population decline
• University dorm population increase vs. population decline
• Review Estimates @ http://ncds.osbm.nc.gov
• Constructive comments with backing information
• Municipalities Can Challenge Estimates After Certification (But Process is Limited) ‐ See OSBM Budget Manual for Process
https://www.osbm.nc.gov/state‐budget‐manual
26
Population Projections (July 1, 2019 – July 1, 2039)
• Forecast models of time series trends (1990‐2018)• ARIMA or Exponential Smoothing
• Total Population• Total Race Group• Total Hispanic Origin
• Cohort‐Component Model to “Age” population• 3‐Year Average for fertility• Survival Rates from 2010• Net Migration (Trend Based on Total – Expected)
• Age‐Specific Rates from 2000‐2010• Projection Contents
• Total by Sex & Age (Single Years of Age, 0 – 99 and 100+)• Race by Sex & Age Groups (American Indian/Alaska Native, Asian,
Black, White, Multi‐Racial)• Total by Hispanic Origin (Total, White, Non‐White)

Census 2020
https://census.nc.gov/
• Constitutionally mandated headcount • Article I, Section 2 & 14th Amendment• All 50 states, District of Columbia, Puerto Rico, and the Island Areas.• All ages, races, ethnic groups, citizens and noncitizens
• Used for Apportionment • determination of state representation (House, Electors)
• Used in redistricting • re‐drawing of boundary lines for federal, state, and local political boundaries
• Affects federal and state funding
• Used for decision making

Always verify your boundaries!
Census maps are generated fromdecades of geographic updatesusing many different technologies.
Do NOT assume that your Census boundaries are correct because you have not annexed recently.
U S Census Bureau – Boundary & Annexation Survey (BAS)
https://www.census.gov/programs‐surveys/bas.html
Census data is the foundation of apportionment in the US House of Representatives, drives over $1,600 per person per year in federal funding to North Carolina, and informs local planning, economic development, and services.
Preparation – LUCA, BAS, PSAP, New Construction – is very important
Preparation without Participation is wasted effort
Local preparation partnerships – Complete Count Committeesinvolve trusted local faces in promoting Census participation
https://census.nc.gov/data‐and‐visualizations
Participation Is The Goal

Fiscal Impacts of the Census – State
• Municipal State Street‐Aid (Powell Bill) Allocations• 75% of funds ($110.5 Million)• Per Capita: $19.56
• Department of Revenue • Sales & Use Tax Distributions Using Per Capita Method:
• $1.4 Billion • Per Capita: $184.67
OSBM Certified Population Estimates Require Accurate 2020 Census Count!

$1.5 Billion in State Funds Distributed to Municipalities & Counties
Estimated amount of funds distributed annually to North Carolina based upon OSBM certified population estimates (2 largest state revenue allocations).
Census staff are meeting with local elected leaders – state, county, and municipal – to encourage the formation of CCCs.
Anyone can form a CCCChurches, schools/campuses, non‐profits, neighborhood,Businesses, clubs/organizations, … anyone!
CCCs are NOT identical!
CCCs will vary in organization and operation because the communities they serve vary
All CCCs should – Assess, Plan, Budget, and Communicate
Complete Count Committees ‐ CCCs
