Acknowledgment

This research and publication were made possible by a grant from the Community Partnership Committee through its Applied Research Initiative on access to telecommunications services in California’s underserved communities, with support from ZeroDivide. The Community Partnership Committee was formed by eight coalitions of 134 community-based organizations and SBC (now AT&T) to serve underserved communities throughout California after the SBC/Pacific Telesis merger in 1997.

This growing reliance on ICTs has infused the concern over an emerging digital divide with other issues, such as economic development, public safety, health, transportation, and other quality of life indicators. This is especially problematic because digital divide manifests not only across generational and gender differences but also

As Table 5 illustrates, the percentage of Latinos in a census tract is highly and positively correlated with lower educational attainment (and, negatively, with higher educational attainment). This phenomenon is reversed in the case of Non-Hispanic White population. While African Americans display similar conditions as Latinos, the correlation values are smaller (possibly

Methodology and Findings

As Table 102 indicates, SES I has relatively

low correlation values across all variables. As implied previously, this variable has lower ability to provide a clear indication of socioeconomic divide in the state. This is partially caused by the fact that it includes service occupations, which could include a range of income potentials and spatial distribution. As such, while the index may be useful for understanding how socioeconomic variables are structurally related, it is less useful for understanding the emergent fractures within our social geography. Contrary to this variable, SES II and SES III are able to more clearly provide the observed social and economic differences. As indicated before, SES II is capable of identifying areas with a significant concentration of highincome population engaged in professional occupations, and SES III can identify rural areas with a large number of people employed in farming, fishing, and forestry occupations. Looking across Table 10, it is clear that SES II is positively correlated with desktop and laptop ownership (slightly higher for the latter), having more than two cell phones, access to the Internet via cable and DSL, using various modes of instant messaging, e-mailing, and all types of Internet usage. It is interesting that ownership of one cell phone is correlated negatively with this variable. This suggests that in areas with highsocioeconomic status, households are not likely to house a population that relies on a single cell phone and each member will have his or her own cell phone. Surprisingly, this variable (having access to only one cell phone) appears to be capable of distinguishing areas with a large number of lowersocioeconomic households from others.

Internet usage variables with the highest correlation values with SES II are online shopping, e-mailing, online banking, and sending pictures. This suggests a high reliance on the Internet for communication and economic transactions among the well-to-do households in California. As Table 10 indicates, these households live in areas with a particular racial and ethnic structure. The high positive correlation between SES II and NonHispanic White, a smaller, but positive, correlation with the Non-Hispanic Asian population, and a negative correlation with all other racial and ethnic groups confirms that the emergent digital divide in California may have a particular racial/ethnic dimension, as well. This is further illustrated by SES III, which appears to be the opposite of SES II in its patterns of correlation with technology variables and racial/ethnic indicators. In fact, most technology variables are negatively correlated with this index, while concentration of Latinos is positively correlated. Since SES III increases in value where rural populations are found, the results can clearly suggest that a ruralurban divide is exacerbated by social class and racial/ethnic differences. SES III correlates positively with having one cell phone, zero wirleines, and a Latino population, providing a particular picture of digital divide in California. As the Latino population in a rural census tract increases, access to cable and DSL, as well as any chance of using the broadband for any Internet activity, diminishes. Households in these areas are more likely to rely on a single cell phone, having no access or no need for wirelines (note the positive correlation between having one cell phone and zero wirelines).

this confirms that having a single or multiple cell phones is an important predictor of socioeconomic status. In fact, as Table 10 illustrates, while having one cell phone is negatively correlated with all other technology access indicators, it is positively correlated with percentage of Latino, NonHispanic African American, and Non-Hispanic Native American populations. Since owning a desktop or a laptop is the first step toward using the Internet, it is important to note that there are some differences between the two. As the number of households with laptops increases in an area, the level of advanced Internet usage increases. This is particularly visible in the higher correlation values for video downloading and watching Internet TV. While this may be driven by the underlying socioeconomic factors (laptop owners versus desktop owners), the difference nonetheless translates to issues of mobility and higher utility, factors that can be improved as the price for laptops approaches those of desktops. In terms of connectivity, Table 10 makes it clear that in areas where a large number of households employ dial-up services to access the Internet, usage of various Internet services remains minimal. At such low speeds, it would be nearly impossible to engage in sophisticated usage of important online functions, such as shopping and banking. Internally, variables defining various types of Internet usage are highly correlated. This suggests that Internet users who use cable or DSL are more likely to consume all that the Internet can provide. The only exceptions are those who rely on a large bandwidth, such as downloading videos or watching Internet TV. As such, selected technology

variables can be used to create a typology (or grouping) of Internet usage (by census tract). To illustrate this, I ran statistical analyses to examine the structural relationship between these variables. Readers need to be reminded that since the data used for this report represent census geography, the grouping simply suggests how areas can be grouped, based on how their residents use various Internet services. Table 11 represents the results of a factor analysis on 15 variables. Because this is indeed a variable reduction technique, we can use the results to understand how particular variables group together (through their loading levels on each new complex Table 11.

variable or index). The result of this analysis suggests that the 15 variables could help construct two indexes, collectively explaining close to 94.5% of the variance in the original data. These variable groupings reflect two types of Internet usage: common applications (such as e-mailing, banking, shopping, sending pictures and videos, and playing games alone) and specialized usage that requires high-speed connection (Internet videos, games, music, streaming audio, multiplayer games, visiting and publishing to community, Internet TV, and streaming video). Since the unit of analysis is a census tract, this grouping pattern suggests that not only is there a distinct geography of Internet usage but also this pattern is driven by socioeconomic status of an area, which affects its prevalent mode of connection to the Internet, the degree of need for particular application, and cost associated with more advanced applications (and technologies). Based on initial findings, I ran a second factor analysis, including all the pertinent technology variables, attempting to create a composite technology index that can provide an overview of the geography of access to technology the state. Table 12 provides the results of this analysis, highlighting the degree to which a typology of access to technology can be created. The three extracted composite indexes collectively explain 96.6% of the variance in the 40 variables in this study.3

The three indexes provide an interesting grouping of census tracts by technology indicators. The first index includes the largest number of technology variables and, as such, should be treated as the technology index for mapping and further analysis. It portrays a high loading pattern by all variables other than 11. These 11 variables have higher loading values on Indexes II and III, suggesting a clear division between neighborhoods and their

pattern of access to technology. For example, the second index includes having access to one cell phone, one desktop, cable connection to the Internet, and zero or one wireline. This confirms the earlier findings regarding the number of available cell phones per household. Given that having only one cell phone per household produces the highest loading value on the second index and is missing from the first index (having achieved a loading value below 0.3), we can state with certainty that this variable is an important identifier for the level of access to technology. In other words, in neighborhoods where a large number of households have only one cell phone, access to other technologies seems to score low. Note that all the Internet usage variables scored lower on the second index than on the other two. The third index provides further evidence to what was discussed regarding the typology of use (see Table 11). Once again, this statistical analysis illustrates how high-end uses tend to group together, creating an index that not only distinguishes itself from the second index but also from the first. In other words, there is a distinct grouping of census tracts that differentiates neighborhoods with users of instant messaging with voice, downloading video content, downloading/purchasing games, downloading/ purchasing music, listening to streaming audio, visiting/publishing to online community, and watching Internet TV live from others. Figures 57 through 57b illustrate the geographic structure of these three indexes. The first index, which appears in Figure 57, helps identify areas where a significant number of residents have access to a host of technologies and Internet usage. Areas with higher

meant that if a tract scored uniformly low across all variables, it could only achieve a value of 26 on the new index. If it achieved the highest score on all variables, a census tract would receive an index value of 78. The result for all census tracts in California revealed that the lowest achieved score is 29 and the highest is 75. These values represent the Cumulative Technology Index for the State. Figure 58 illustrates the geographic distribution of this index, illustrating that areas with the highest scores are more likely to be located closer to the coastal regions in the Bay Area, extending from Contra Costa to Santa Clara and Marin to San Mateo counties, and in Southern California, extending from Ventura to San Diego, including the southwestern region of San Bernardino and the western section of Riverside counties. With a mean score of 52 and a standard deviation of 11 for the state, it is expected that about two thirds of all census tracts achieved a score that ranges from 41 to 63.6 However, 979 census tracts had values

score very high on this score. This is also true for two small urban corridors: one extends from Hollywood through West Hollywood, Beverly Hills, and along Wilshire Blvd. to UCLA and Santa Monica and the other, along the 101 freeway corridor from Burbank to Sherman Oaks. Other pockets of high scores also appear in a number of other cities in Los Angeles, Orange, San Diego, Ventura, and Riverside counties. In the Bay Area, few census tracts in the cities of Fremont, San Francisco, and San Jose score high on this index. As Figure 57b illustrates, very few tracts achieved a high score on this index, clearly distinguishing various concentrations of high-end users. From a statistical perspective, while the first technology index, which includes access to a significant majority of ICTs, is highly correlated (i.e., Pearson correlation=0.71, significant at the 0.01 level, 2-tailed) with the second socioeconomic status index (i.e., areas with a large number of educated households with professional occupations), the second technology index,

exceeding 63 (or one standard deviation above the mean), 404 of which were located in the three counties of Los Angeles, Orange, and Santa Clara (see Table 13). Collectively, the 979 tracts had a population of close to 6 million, which accounts for 16.2% of the total population in the state. Nearly half of the residents of these tracts were NonHispanic White, while 5.3% were Non-Hispanic

African American, 18.4% were Non-Hispanic Asian American, and 22.6% were Latino. Comparing these values with the overall racial and ethnic structure of the state (see Table 1) suggests that the population residing in tracts with the highest levels of access to technology is disproportionately NonHispanic White and Asian.

This is slightly over 1% of the total population and about 5% of all Non-Hispanic White residents of the county. In contrast, these low-scoring tracts house over 1.5 million Latinos, making up 15% of the county population and about 32% of its total Latino residents.

Collectively, these 228 tracts house 1.1 million individuals, who are largely Latino (64.6%) and NonHispanic African American (9.5%). However, in counties such as Butte, Humboldt, San Luis Obispo, and Ventura, more than half of the resident population of these tracts is Non-Hispanic White. Counties where Latinos make up more than half of the population in the identified tracts include Fresno, Imperial, Kern, King, Los Angeles, Madera, Merced, Riverside, San Bernardino, San Diego, San Joaquin, Santa Barbara, Siskiyou, Stanislaus, and Tulare. Among these, Los Angeles, San Diego, Kern, Riverside, Tulare, and Fresno house the largest number of Latinos (i.e., close to 83% of the Latinos in the selected 228 census tracts, or 600,000, live in these six counties). The aggregate ranking pattern on the 26 technology variables for these 228 tracts are shown in Table 16. It is clear from this table that these areas collectively rank

Concluding Remarks

This study focused on an in-depth analysis of access to information and communication technologies (ICTs) in California. Using census tract data from 2007, we were able to provide a detailed visual and statistical assessment of the nature of digital divide in the state. This allowed us to create statewide and county-level maps and analyses that identified the patterns of inequity by social, economic, racial, ethnic, and geographic indictors. While the main body of the report displayed maps at the state level, we prepared an Appendix that contains a set of 35 maps for each county in the state. In all, over 2,000 maps have been created to provide readers with a visual tool to assess the spatial structure of access to ICTs in the state.7

Our findings illustrate the degree to which Latinos and Non-Hispanic African Americans remain isolated from advancements in the use of ICTs and the information and services they offer. In the case of Latinos, this takes both a rural and an urban dimension, suggesting that as a group, they face many obstacles in accessing technology, regardless of where they live. It was also illustrated that, within an urban context, African Americans in particular locations, such as Alameda and Los Angeles, remain equally and, in some cases, more pronouncedly isolated from what the information technology can offer. The racial/ethnic dimension of the digital divide is an important concern, especially when we consider the degree to which this factor has correlated with socioeconomic status. As indicated in this report, while less homogenous places are not necessarily always low-income minority neighborhoods, many African American and Latino majority areas experience lower-socioeconomic status. This was clearly illustrated when we discussed the concept

of diversity (i.e., entropy index). The lingering question of race/ethnicity and its geography becomes clearly important as we consider the issue of digital divide. For a state that has attracted many immigrants and minorities over the last few decades, allowing it to become one of the most diverse places in the world, the paradox of segregating in the midst of diversity is an ongoing challenge. In the case of digital divide, then, it should not come as a surprise that the emergent spatial patterns are strongly influenced by the geography of race and ethnicity. In fact, what is ironic about the state of digital divide in California is the degree to which diversity status in a census tract is related to the observed level of access to technology. As discussed earlier, an entropy or diversity index allows us to measure the degree to which various racial and ethnic groups cohabit in an area. The larger the value of this index, the higher the level of diversity would be. To be sure, this index was shown to be negatively correlated with Latino and Non-Hispanic White populations and positively with Non-Hispanic Asian and African American populations. This meant that census tracts with a high-diversity index were more likely to house a large number of the latter groups and less of the former. With that information in mind, it was surprising to discover that our cumulative index of access to technology was positively correlated with the diversity index! In other words, the higher the diversity level, the more likely an area was to receive a high score for access to various technologies. Interpreting this in a positive manner, it means that in areas with a higher socioeconomic status, in which a mixture of racial and ethnic groups, particularly Asian

Concluding Remarks

Americans and African Americans, live together, access to technology is more prevalent. Interpreting it negatively, less diverse places, where lowincome Latinos are more likely to reside, are more likely to experience low levels of access to ICTs. This means that the path to digital equity is not that different from the path to social justice. Space has become the container of our social, cultural, and economic relationships, encapsulating our structural differences and inequities. To ameliorate these sociospatial injustices, we need to accept that “place” matters, places are marred by the nature of our past and present relationships and sociopolitical dynamics, and places reproduce these conditions due to years of disinvestment and neglect. From a policy perspective, it means that to improve the state of digital divide, we need to understand its social, cultural, economic, and demographic underpinnings; and, we need to construct our solutions in a systematic manner that dovetails social justice efforts, economic development plans, educational reforms, and all other progressive social policies. Digital divide does not occur in a vacuum, unaffected by social processes or a social context. In fact, it would be a great mistake to assume that digital divide is merely a technological problem. The geography of digital divide, as presented by this research, suggests that to produce sustainable solutions for the existing patterns of inequitable conditions, we must deal directly with the sociospatial contexts that produce them. Without changing these contexts, a lasting change cannot occur. For this reason, and based on the findings of this research, we offered a particular methodology and

a set of recommendations for to dealing with the problem of digital divide in the state. In summary, these are as follows: I.

Form public-private partnerships to assess

the actual patterns of access to technology, using subscription and technology application data. II. Identify and prioritize areas for short-term and long-term policy interventions. A. For this study, we identified two groups of census tracts: 1) One group houses a population, whose access to ICTs is only slightly below the state average (see Figure 59). For these tracts, we recommend the following strategies: – Address infrastructural inequities to assure high-speed connectivity – Ensure that access is not hindered by cost – Provide educational resources regarding the use and benefits of the Internet – Expand subscription and use of cell (through a public-private partnership that brings about less costly services and wider geographic coverage) 2) The second group of tracts housed a population with some of the lowest levels of access to the ICTs. For these tracts, we recommend strategies that focus on expanding the existing physical infrastructure, access to services, and enhancing the social capital of
