26                <h3>Population Estimates</h3> The population estimates used for population-based birth rates come from the U.S. Census. Currently HHDW has loaded the Vintage 2020 estimates, which are based on the 2010 Census since the 2020 results haven't been released. Once the 2020 Census results are available, the population estimate file will be updated. Note that birth rates may differ slightly once the population estimates are updated later this year.

31                <h3>New Primary Care Service Area Dimension</h3> We have added a new geographic dimension to the Birth Module
32                to cover primary care service areas. Primary care service areas were created to describe the delivery of
33                primary health services in the State of Hawai'i through participation of multiple stakeholders in the early
34                1990's. The rural health associations of the Hawai'i, Maui and Kauai Counties delineated rational service
35                areas under their respective jurisdictions. Neighborhoods were clustered into primary care service areas to
36                provide information below the county or island level with demarcation between adjacent neighborhoods. Census
37                tracts were used in defining these areas due to their availability in census and vital statistic data.

53                <h3>New Cell Suppression Criteria</h3> Cell suppression criteria have changed. In accordance with data use
54                restrictions set forth by Hawai'i State Department of Health (DOH) and the National Center for Health Statistics (NCHS),
55                cell counts of fewer than 9 events and rates based on counts of 9 or fewer will be suppressed, and rates based on
56                counts of less than 20 will be regarded as unreliable and will also be suppressed. Suppressed data is denoted with
57                a double asterisk (**).

62                <h3>Changes to the Birth Certificate</h3> A new birth certificate data collection form was implemented
63                in Hawai'i in 2014.  This new form and some procedural changes in how some data elements are captured
64                resulted in discernable differences in some of these data elements before and after the change. In
65                prior years, infant gestational age at birth was calculated based on the date of last menstrual period
66                as reported by the mother. As of 2014, gestational age is based on the health care provider's assessment;
67                therefore, dimensions based on gestational age cannot be trended. Accordingly, HHDW has created two new
68                dimensions starting in 2014:
69                        <ul>
70                                <li>Infant's Gestational Age (2014+)</li>
71                                <li>Trimester Prenatal Care Began (2014+)</li>
72                        </ul>
73                <br/>
74                Birth method data (Birth Type) has also been impacted by this data collection change. We are working with
75                the Office of Health Status Monitoring at DOH to determine the best way to handle these changes. In the
76                meantime, analysis by birth method is limited to 2000-2013.
77                <br/><br/>

79        <h1>All Years</h1>

81                <h3>Population Estimates for Population-based Rates</h3>
82                Annual population estimates are extracted each year from the U.S. Census, Population Division, Annual County Resident
83                Population Estimates. These estimates change each year and provide the denominator for the crude birth rates, fertility
84                rates and teen birth rates, by age, sex and census race, for the years 2000-2019.
85                <br/><br/>
86                However, population estimates for Hawai'i-specific race/ethnicities (DOH Race/Ethnicity) are not reportable for
87                individual years, so a special 5 year aggregate population estimate file was created for Hawai'i, by the Data Products
88                Development Branch, American Community Survey Office, U.S. Census Bureau. This 5 year aggregate (2010-2014) file was used to
89                create a single average annual population estimate, which does not change and is used for all population-based rates by
90                DOH Race/Ethnicity for the years 2010-2019.
91                <br/><br/>             
92                Because HHDW uses two different population estimate files, birth rates may vary slightly depending on which category
93                you select your birth rate indicator from - Rates by Census Race vs Rates by DOH Race/Ethnicity. Census Race and DOH
94                Race/Ethnicity rates should not be compared directly.
95                <br/><br/>             
96                <h3>Residence</h3>
97                Data can be analyzed geographically by mother's residence or infant's place of birth. Mother's residence is based
98                on the address provided on the birth certificate as the place where the mother resided at the time of the birth.
99                Military members and dependents who live in Hawai'i at the time are classified as residents. Visitors who give birth
100                while in Hawai'i but do not reside in Hawai'i will not appear in queries by Mother's residence.
101                <br/><br/>             
102                There are two measures for capturing geography in the Birth Record - zip code and census tract. School complex and
103                community are based on zip code and primary care service area is based on census tract.
104                <br/><br/>             
105                Infant's birth location includes all live born infants in Hawai'i regardless of the mother's place of residence.
106                Infant's birth location will not always correspond to the mother's place of residence; for example, an infant can
107                be born in Honolulu to a mother who resides in Kauai.
108                <br/><br/>
109                <h3>Race/Ethnicity Data</h3>
110                The birth certificate allows for up to 4 race/ethnicities to be captured for both the mother and the father.
111                The DOH Office of Health Status Monitoring (OHSM) uses the following algorithm to code a single race/ethnicity for
112                each individual. Ethnicity of the child is based on the ethnicity of the father. It is based on the ethnicity
113                of the mother when the ethnicity of the father is unknown.
114                <br/><br/>
115                Only one ethnicity is coded from the actual certificates. If more than one ethnicity is listed on the
116                certificate, the following rules apply:
117                        <ul>
118                                        1.      If Hawaiian is one of the multiple ethnicities listed, Part-Hawaiian is coded.<br/>
119                                        2.      If a non-Caucasian ethnicity is listed with a Caucasian ethnicity, the non-Caucasian ethnicity is coded.<br/>
120                                        3.      If there is more than one non-Caucasian ethnicity listed, the first one is coded.<br/>
121                                        4.      If there is more than one Caucasian ethnicity listed, the first one is coded.<br/>
122                        </ul>
123                <br/>
124                In HHDW, the most granular level is the program race/ethnicity (PRG) which rolls up into the DOH standard
125                race/ethnicity (DOH), which rolls up into Census race reporting categories (Census). The table below illustrates
126                how the data is aggregated.
