The 2014 CNMI Broadband Survey showed change in broadband use on Saipan, Tinian, and Rota between 2011 and 2014. The results of the two surveys have been released. The Central Statistics Division of the CNMI Department of Commerce added additional elements to the 2011 survey questionnaire in developing the 2014 questionnaire. Because CNMI had not had a labor force survey since the 2010 Census, and since the broadband survey was large enough to avoid major sampling issues, staff added educational attainment and labor force participation for each household member in order to get additional information about the labor force situation on the three islands.
The original State Broadband Initiative (SBI) was a part of the American Recovery and Reinvestment Act (ARRA), which is more commonly referred to as the Stimulus. The SBI's goal was to create a comprehensive broadband map that covered every state and territory in the United States. The uses of the map are manifold: as a tool for consumers, a centralized compilation of information for the federal and state governments to use in matters of regulation and public policy, and as a trove of data for think tanks and research institutions.
In addition to the mapping aspect of the SBI, there was also a planning component. The goal of the planning sect ion was to create a comprehensive plan to understand the extent of broadband usage and ownership, barriers to adoption, and to create a plan to overcome these barriers and to boost broadband usage through work with nonprofits, local governmental agencies, and public policy advocacy.
For the initial survey in 2011, One Global Economy was selected by the Commonwealth of the Northern Mariana Islands (CNMI) Department of Commerce to fulfill the broadband mapping grant that was awarded to them by the National Telecommunications and Information Administration (NTIA). One Global Economy is a global nonprofit community development organization whose goal it is to help low-income people gain greater access to and utility from broadband Internet connect ions.
One Global Economy's final deliverable was a comprehensive report that will assess the current state of broadband in CNMI by determining how fast the connect ions are, what proportion of the population has access to broadband, what proportion of the population subscribes to broadband; identifying the most common barriers to broadband adoption and use; and creating a blueprint towards greater broadband usage wit h recommendations for the local governments of the three most populated islands: Saipan, Rota, and Tinian, the federal government, local NGOs, local Internet service providers, and the people of CNMI.
The first step in this process was to draw upon the information and maps that the local telecom providers had to share with the entities undertaking the mapping project. These maps showed the approximate reach of where each telecom can offer service, what the maximum advertised upload and download speeds are, and what type of service they offer-DSL or cable, for example. These maps gave us a rough lay of the land and provided us with a good jumping off point for further research.
Using these maps information as a starting point, and drawing upon the knowledge of a local liaison, we were able to hold a series of 14 community meetings and focus groups. The main purpose of these meetings was to help us customize the NTIA's community broadband survey to make it locally relevant, culturally sensitive, and provide us with more detail about the experience of going online for the people of CNMI. For instance, knowing that many young people in CNMI get online at the Mobil Station in Garapan helps get a better understanding of the role of unsecured wireless networks in public places in the online ecosystem of Saipan.

National Coverage of the Commonwealth of the Northern Mariana Islands.
The 2014 Broadband Survey was developed to see change from 2011. Most of the questionnaire was the same as the previous one. However, because the CNMI had not had a labor force survey since the 2010 census, CSD decided to add additional variables to assess the current labor force situation. And, in order to obtain sufficient households for labor force participation and unemployment, the sample size was about 4 times as large as the 2011 sample. Also, since the 2011 questionnaire took up many pages, slowing coding and keying, the questionnaire was tightened both for easy of collection, coding and keying, and also to have it conform to regular CSD convent ions in questionnaire design.
Hence, the front page contained the geographic identifiers. Then the roster of household members included all members, their relationship to the head, sex, age, educational attainment, and labor force participation. After that, the person selected for the broadband quest ions followed on the backside of the questionnaire. Only one person was selected for the broadband items.
As in 2011, all residents of CNMI inhabit the three southern islands of Saipan, Tinian, and Rota. The northern islands were once inhabited but have been evacuated due to seismic and volcanic activity (although recently a few people have returned to at least one of them). In 2014, 1,542 surveys were conducted in total, 1,184 with residents of Saipan, 154 with residents of Tinian, and 204 with residents of Rota. Within these unit s, Saipan had 3,707 people, Tinian had 547, and Rota had 589.

In 2011, One Global Economy created a survey aimed at understanding factors that influenced broadband access and use based on community input from a series of town hall meetings conducted in local areas throughout the Northern Marianas Islands (CNMI). One Global Economy contracted with JSB Consulting, a locally based survey firm to carry out the survey. JSB Consulting collected the data using recruited enumerators. These local surveyors conducted the surveys in person, in respondents' homes, by asking respondents quest ions in the respondents' preferred language.
Respondents were selected to be representative of the population of CNMI, which consists of three main islands: Saipan, Tinian, and Rota. JSB Consulting (JSBC), as required under its contract with One Global Economy, selected a total of 867 Household (respondents) on Saipan, 100 on Tinian, and 100 on Rota, for grand total of 1,067 respondents. Although the task order under the contract calls for 1000 respondents, JSBC selected and additional 67 household
(respondents) for Saipan to ensure that all areas on the island of Saipan are covered/represented. Selected sample dwellings that appeared vacant (upon survey period) were substituted with another occupied dwelling unit from the listing.
On the island of Saipan, a stratified sampling approach ensured that respondents proportionally represented the geographic distribution of the island's population. JSBC drew the samples by using the geographic boundaries assignments areas (AAs) and the block numbers within the AAs. The AAs and block numbers are the geographic numbers assigned by the U.S. Census Bureau and used in Censuses and Survey operations in the CNMI.
The Central Statistics Division has retained and maintained the same geographic structure since its inception. On Saipan a total of 328 assignment areas (AAs) out of 497 AAs were drawn. From these selected AAs, JSBC then randomly selected specific dwelling unit s in accordance with the population of those AAs. More dwelling units were drawn from AAs with larger populations, and fewer were drawn from those with smaller populations. Once a dwelling unit
was drawn, it was then assigned to the field staff for enumeration.
On Rota and Tinian where only 100 sample subjects on each island were needed, the collect ions methodology was a straight forward random sample. Since each island has only a little over 600 hundred dwelling units, approximately 1 out of every 6 dwelling units was selected for inclusion in the sample. Tinian and Rota each have only two main villages; on each island, 50 respondents from these main villages were selected for the sample. The collection method used was the "keep right" approach, using the AA and block maps. The "Keep Right" approach is one is working on a block (the smallest geographic unit in data collection boundary) the enumerator/survey takers keep themselves on the right side of the road/boundary from any designated starting point. This prevents any selected house from being missed or going out of the designated boundary. This approach was used to ensure that the field staff does not cross over a certain boundary to cause a problem or any confusion in the process.
With each survey, surveyors noted the location of the respondent's dwelling according to the designated geographic areas. While respondents were also asked to say where they lived, this official designation allowed for more uniform aggregation of the data according to legal boundaries.
The enumerators collected the data at the selected housing units. Coders then coded certain items, and CSD office staff entered the data. For 2011, One Global Economy analyzed the data using SPSS, performing logistic and linear multivariate regression analyses, bivariate correlations, and cross-tabulations to better understand the patterns in the data and the relationships between key variables. Cross-tabulations and bivariate correlations showed the
overall distribution of the population in relation to certain factors, and also the general relationship between different variables. Multivariate regression analyses were also used to determine the relationships between relevant variables after controlling for (holding constant) other related factors, and also to assess the statistical significance of these relationships. For example, simple correlations may show that additional years of education and higher income are
each directly correlated with broadband adoption in the home. However, since more education and higher income are themselves often related, it is difficult to tell whether it is income or education that plays a more significant role in determining whether a household adopts broadband. A multivariate regression analysis can show whether income or education has a larger and more significant impact on broadband adoption.

Total Overall Response Rate:
CNMI: 96% (1542 / 1600)
Saipan: 98% (1184 / 1200)
Tinian: 77% (154 / 200)
Rota: 102% (204 / 200)
In order to obtain figures that resembled census numbers, the CSD staff decided to weight the individuals in the sample on the basis of their age and sex. CSD decided that the current population - the population in mid-2014 - was about the same size and structure as the 2010 population of about 54,000. So, staff made two matrices, one 5-year age groups by sex from the Census, and the other 5-year age groups by sex in the broadband survey. Then, each of the census cells was divided by the sample cell to obtain a weight. These weights were then added to the records using a CSPro edit program.
