Introduction
Examining the larger demographic and economic changes that have occurred in the county will help United Way volunteers understand the reasons behind some of the needs that currently exist and project emerging needs. From this understanding can come a more responsive allocations process and more effective funding for the needs of Marin County's increasingly diverse population.
This overview is necessarily broad and cannot document all of the changes that have occurred in the past ten years. This chapter focuses on the key changes and trends that have shaped life in Marin County's diverse communities. The changes have been rapid and are expected to intensify in the future. They have affected employment, schools, public finance, demand for basic public services, and the organization of the nonprofit service sector. The following aspects of Marin County are explored in this chapter: population growth; race, ethnicity and national origin; age; income and poverty; and housing.
Perhaps the most important information presented here concerns the changing demographics of the County. By itself, information about the racial or ethnic background of the population may mask more important meanings. Only by combining such variables as ethnicity, education, income, language and age can a more comprehensive and useful picture emerge. This chapter attempts to show some of the deeper meaning behind racial or ethnic differences. Data presented in subsequent chapters will identify the race of those experiencing particular problems since the ethnicity of clients is a common way of reporting data. While race is an important dimension for decision-makers to keep in mind, it is only one of the many factors that influence the need for services and the ability to get them.
Another limitation of the material presented here is that the
time periods covered vary. For example, the Census describes
the population as of 1990 with the exception of income, which
is based on 1989 earnings. In every case, this report presents
the most recent information obtainable, even though it may not
be strictly comparable with other sources.
Population Growth
As is the case with most demographic measures, Marin County's
overall population growth masks highly significant regional differences.
From 1980 to 1990 the county's population grew 3%. Communities
in the four key areas of interest in this report, however, experienced
substantial population increases. San Rafael remained the largest
city in the county growing 8% over this period and Novato, the
second largest city, matched that growth rate. Together these
cities comprise 40% of Marin's total population.

Marin City grew 25% from 1980 to 1990, rivaling the California state average and reversing the modest 1% decline it posted the prior decade. Other high change areas not listed in Table 2.1a included Santa Venetia (+18%), Tamalpais-Homestead Valley (+13%) and Tiburon (+13%); several communities experienced significant population declines including Ross (-28%), Marinwood (-21%), Belvedere (-12%) and Fairfax (-6%).
Novato and San Rafael, the largest cities in the county, each grew 8% from 1980 to 1990. San Rafael's growth was intensely concentrated in East San Rafael (census tract 1122). The population in this community increased 55% over this period (seven times faster than city-wide growth), launching it from being the 5th largest neighborhood in the city in 1980 to being the largest in 1990. However, the population of East San Rafael reported by the 1990 U.S. Census is widely considered by public and nonprofit organizations familiar with the area to be seriously underestimated. The Canal Community Alliance, a prominent social service agency serving the area, suggests that an educated guess would place the neighborhood's population at around 10,000. Other estimates of the neighborhood's population range from the Census figure of about 8,000 up to a high of 12,000. By these estimates, then, it is conceivable that the actual growth of East San Rafael over the decade was much higher, perhaps on the order of 90-95%.
Like San Rafael, West Marin also experienced highly localized growth. While the overall population of this region increased 4% over the period, the bulk of this growth occurred in San Geronimo Valley (census tract 1130) which grew 5%, and Inverness/Olema (census tract 1322) which increased 32%. Growth in West Marin offset stable or negative growth in the rest of the region. These declines are reflected in the fact that the combined population of San Geronimo Valley and Inverness/Olema accounted for 40% of total population in West Marin in 1980; by 1990 they accounted for 46% of the entire region's population. Nicasio, Pt. Reyes and other communities in census tract 1330 in West Marin recorded -6% decreases in population.
The localized growth that has occurred in Marin County since
1980 has major implications for projected population growth over
the next 20 years. According to the Association of Bay Area Governments
(ABAG), total Marin County population is expected to grow 17.5%
between 1990 and 2010. Novato and San Rafael are expected to
record 23.2% and 23.6% growth rates over that period, respectively.
Given the rapidly growing, young adult population of East San
Rafael, growth of this neighborhood could easily be highest in
the county again from 1990 to 2010.
Race, Ethnicity and National Origin
Although in comparison with other Bay Area counties Marin County
remains a largely "white" county, a more in-depth examination
reveals significant changes in the county's racial composition
between 1980 and 1990. According to Table 2.2, Whites as a percentage
of total population fell from 93% in 1980 to 85% in 1990 when
Hispanic is treated as a racial category. In 1990, Hispanics
were the second largest racial/ethnic group in Marin County (7.8%),
followed by Blacks (3.3%), Asian/Pacific Islanders (3.9%) and
individuals selecting "Other" as their racial category,
which in this case includes American Indians, Eskimos, Aleutians
(0.5%). Table 2.2 also illustrates the significant differences
in racial distribution among Marin County communities. The majority
of Marin City's population is Black, and over the course of the
decade, East San Rafael's majority population shifted from White
to Hispanic. In fact, 58% of the county's Hispanic population
resided in San Rafael and Novato.
Area | Total Population | Percent White | Percent Hispanic | Percent Black | Percent Asian or Pac/Is | Percent Other Race, Not Specified |
| United States | 248,709,893 | 75.6% | 9.0% | 11.8% | 2.8% | 7.3% |

Significantly, growth in Marin County's total non-White population occurred over this decade almost exclusively in San Rafael and Novato, which are also the largest communities in the county and which had the highest growth rates over the decade. The White population in Marin actually declined about 2.5% over this period while individuals identifying themselves as Hispanic rose 93%, Blacks grew 45%, Asians/Pacific Islanders increased 44% and "Other" races grew 164%.
Again, the rate and concentration of change in certain areas of Marin County is key to understanding change in this county. While the overall Hispanic population of San Rafael increased 3-fold to over 14% of the city's population in 1990, much of that change was intensely located in East San Rafael. The racial and ethnic composition of most San Rafael neighborhoods remained largely stable over this period, except in East San Rafael where the population changed from 4.8% Spanish (the term used by that Census) to 47.4% Hispanic in 1990. This was accompanied by a decline in the percentage of whites from 77% in 1980 to 34% in 1990 (after adjusting for Hispanic as a racial category). The 2-square mile neighborhood of East San Rafael contains 21.2% of the entire county's Hispanic population.
Hispanics are also concentrated in particular areas of West Marin, with fully 75% of the Hispanic population of West Marin residing in census tracts 1330 and 1322. The first of these contains the communities of Fallon, Dillon, Tomales, Marshall, Pt. Reyes and Nicasio, which together are 14.1% Hispanic. The second of these census tracts contains Inverness and Olema, which together have a 10.9% Hispanic population. According to nonprofit agencies familiar with West Marin, Census data collection efforts were particularly inaccurate in West Marin. Rural West Marin holds many hard-to-find households and residents use post office box numbers to receive mail. Census forms, however, were mailed to street addresses. Since the post office will not deliver mail without a box number in West Marin, most Census forms were returned undelivered and the census workers had to solicit completed forms on a house-by-house basis, missing many people. The Dance Palace Community Center, a prominent social service agency serving the area, suggests that a closer estimate of West Marin Hispanics is 1,000 individuals or 7.6% of the total population.
The growth and composition of the Asian/Pacific Islander population also varied significantly across the County. For Marin County as a whole, four groups made up three-quarters of the broad Asian/Pacific Islander category. Individuals of Chinese descent were the largest group, accounting for 33% of all Asian/Pacific Islanders, followed by Japanese with 21%, Filipinos with 13% and Vietnamese with an additional 10% of this category. The other Asian racial groups under this heading were Korean, Asian Indian, Thai, Cambodian, Laotian and Hmong. Hawaiians comprised the entire Pacific Islander group which accounted for 0.3% of the total in the Asian/Pacific Islander category. In East San Rafael, however, over 57% of the Asian/Pacific Islander population was of Vietnamese descent. Chinese were the next largest group with 21.5%, followed by Filipinos with 8.1% and Asian Indians with 6.9% of the Asian/Pacific Islander population.
The racial and ethnic composition of Marin City also experienced significant changes over the decade. Most of the 25% increase discussed earlier occurred among white residents (+119%); Blacks remain the majority in this community with 57.3% of the population, but this percentage is down from 76.4% recorded in 1980.
American Indian/Eskimo/Aleut and Other/Not Specified were the
two remaining categories in the 1990 Census. Both of these groups
were reduced when the ethnicity of Hispanic was treated as a racial
category. Together, they accounted for 3.6% of the County's population.
Age
Marin County's age distribution reflects the national trend toward an older population. Fully 16.7% of Marin's population is 60 or older and this is projected to rise to 22% by year 2000. The percent of Marin residents older than 60 is significantly greater than that of the Bay Area or California, while the percent of children and youth under age 17 is lower in Marin County than in the Bay Area, California and the U.S.
Previously mentioned problems in collecting Census data in West
Marin may be particularly acute in estimating the number of elderly
residents of this area. The Dance Palace Community Center, a
prominent agency serving West Marin, estimated the area's 60+
population at 1,300 individuals or 21.6% of area population.
This estimate dramatically changes the picture of West Marin,
making the ratio of 60+ individuals to area population the highest
in Marin County.

Income and Poverty
Type of Households
In order to discuss income and poverty in Marin County, it is
important to first understand the number and type of households
in the county. Family households account for 71.6% of all households
in Marin County. Married couples with children account for 20.6%
of all households. Compared with other communities in California
and the U.S., Marin County has a high percentage (6.6%) of single
parent households with children. Of these, most single parent
families with children are female-headed. Although there are
many divorced women with children in Marin County with substantial
incomes, the fact remains that nationally women only make about
71% of men's salaries, and Marin County is remarkable for having
a large number of low-wage service jobs and very high housing
and child care costs. The national problem of the concentration
of poverty in female-headed households with children has been
called the "feminization of poverty" and Marin County
does not appear to be an exception to the trend.

Income
Median income figures for Marin County seem to justify the perception
of this county as a place of privilege and wealth. Median household
income in Marin County ($48,544) is 15.0% higher than that of
the Bay Area, 35.6% higher than in California and fully 62% higher
than in the U.S. A closer look shows, however, that entire communities
in this County are low income, not just by County standards, but
by national standards. For example, median income for East San
Rafael households ($32,286) and Marin City households ($28,620)
are 23.5% and 32.2% lower, respectively, than the median income
of all Bay Area households ($42,205). In addition, the median
household income for West Marin masks significant local differences.
According to The Dance Palace Community Center, if the higher-income
Census tracts of 1310 and 1322 are removed from the median household
income estimate, West Marin households have a median income of
$33,058, making the median income of these households lower than
any other area of Marin County except Marin City.

Even more important is the disparity in these communities between family and non-family household income. Nationwide, family household income typically exceeds non-family household income. This relationship is also observed at the state, regional and county levels. A clear illustration of how poverty particularly impacts women and children is the fact that this relationship reverses in low income communities. In Marin City, for example, median family income ($26,767) is 23.7% lower than median income for "Other" households. In a larger context, the median family income in Marin City is 46.4% lower than median family income for the Bay Area and is 24.0% lower than median family income nationwide. East San Rafael shows the same dynamic. Median family income ($29,695) fell below non-family median income by 1990 and continues to trend downward. In broader comparison, median family income in East San Rafael is 40.6% lower than median family income for the Bay Area and is about 15.7% lower than median family income nationwide. Although, West Marin median income is the highest in the county, there is significant variation within the region. In particular, the census tracts 1330 and 1332 have quite low median household income relative to the county.
Poverty is often discussed as if it is a uniform condition of
existence for individuals across communities. However, the cost
of living in Marin County is among the highest in the country
and national poverty indices which do not take cost of living
into account grossly underestimate the amount of poverty in this
county. A more accurate guideline for judging the amount of poverty
in Marin County is the Chart of Upper Income Limits developed
by the U.S. Department of Housing and Urban Development which
define poverty levels within the context of the cost of living
in particular regions of the country.

HUD guidelines show that one-person households in the Bay Area
earning less than $27,950 in annual income are considered low
income. This means that the 22.3% households in Marin County
earning under $24,999 are low or very low income. Even more startling
is the fact that 44.6% of Marin City households and 38.4% of East
San Rafael households are considered low or very low income by
these standards.

Poverty and Race
As is the case nationally, poverty disproportionately affects
minority households in Marin County. More than 42% of all Black
households, 25% of Asian or Pacific Islander households, 37% of
"Other" race households and 34% of Hispanic households
are low or very low income, compared with 20% of White households
that fall into that category. Although households in poverty
can be found throughout Marin communities, there are significant
concentrations of low income households among Latinos, Blacks
and Asians in East San Rafael, Blacks in Marin City and Latinos
in West Marin and Novato.

As discussed previously, the Census data on poverty was based on national poverty guidelines which do not factor in the variation in the cost of living among regions. To provide more accurate and relevant data on the poor, however, the Census provides information on the number of individuals living below 125% and 200% of the poverty level. According to this data, 11,542 individuals "technically" live below the poverty level while more than double that figure, 32,001, live below 200% of the poverty level.
Regardless of which measure is used, Marin County's overall poverty
rate is well below the regional, state and national rates. Important
areas of the county do, however have very high poverty rates.
Over 24% of Marin City residents live below the poverty level
and 41% live below 200% of the poverty level. In East San Rafael,
20% of the population is below the poverty level while more than
twice that number (45%) are below 200% of the poverty level.
West Marin and Novato have fairly low poverty rates, 4% and 7%
of the population respectively, but these figures rise dramatically
to 14% and 21% for individuals living below 200% of the poverty
level.

According to the national poverty guidelines used by the U.S.
Census, Marin County's poor population is slightly older than
in the region, state and nation. Over 63% of the poor in Marin
County are between 18 and 59 and a much higher percentage of the
elderly (13%) are poor in Marin County than in the region or state.
There are important geographic variations in the age of the poor,
however. In Marin City over 40% of the population in poverty

Housing
Rates of homeownership in Marin County closely parallel income differences across communities. For example, 62.1% of housing is owner-occupied in Marin County as a whole, yet only 19.8% of housing in East San Rafael is owner-occupied. Marin City also has a relatively low owner-occupancy rate of 28.8%. Novato registers the lowest vacancy rate of 2.9%. While West Marin may appear to have a relative surplus of housing, in fact the 21% vacancy rate reflects high cost vacation rentals and summer homes. There is a severe shortage of rental housing that is affordable in much of West Marin.
Homeownership rates are a significant indicator of a community's
stability and of the commitment of a neighborhood to preserving
itself. Communities with low homeownership rates suffer relatively
more crime and blight, which perpetuate their low-income status
and exacerbates other social problems often found in these communities.

Overcrowding
One result of overcrowding is the stress it causes on the physical condition of housing units. Landlords are often unwilling to correct problems of wear and tear when it is believed to be caused by overcrowding. In addition, overcrowding creates stress which can be a factor in domestic violence and abuse. Children who live in overcrowded conditions are often unable to concentrate on or complete schoolwork.

of 0.40, which contrasts with the high 0.74 measure in East San
